PURPOSE The MIA FORA
TM NGS HLA typing kit is designed for amplification and sequencing of HLA genes HLA -A, -B, -C, -DRB-1/3/4/5,
-DQA1, -DQB1, -DPA1, and -DPB1 on the Illumina NGS sequencing platform. The MIA FORA software is designed for use as a guide for determining HLA type from the data generated with the MIA FORA NGS HLA library kit. The test is intended for use in a laboratory proficient in handling DNA for amplification and sequencing.
SUMMARY AND EXPLANATION Sequence Based typing of PCR amplified exons of HLA genes is a common laboratory procedure. PCR amplification is used to enrich targeted sequences and the subsequent HLA typing is determined for the selected regions. Other methods such as sequence specific oligonucleotide probe (SSOP), sequence specific primer extension assays (SSP) have also been used to determine HLA typing. The MIA FORA NGS HLA typing system is a novel HLA typing methodology that utilizes the ability to capture all relevant regions of the HLA loci by long range PCR. Nine PCR master mixes that contain all required components to amplify each gene, including enzymes, buffers, dNTPs and primers for long range PCR amplification are provided in the kit. The amplified DNA can then be processed by using the MIA FORA NGS HLA library kit to generate DNA library for sequencing on the Illumina sequencing platform. The kit allows up to 24 samples to be sequenced in a multiplex fashion using the Illumina sequencing platform.
PRINCIPLES OF THE PROCEDURE The MIA FORA NGS HLA typing kit is designed to determine the typing of Class I and Class II HLA loci by sequencing the whole gene or the most informative exons and introns. The MIA FORA NGS HLA typing kit uses long range PCR to capture and enrich the major HLA genes, HLA -A, -B, -C,-DQA1,-DQB1, -DPA1 –DPB1, and –DRB1/3/4/5. The MIA FORA NGS Library Preparation reagent kit generates a library from the amplified DNA for sequencing on the Illumina sequencing platform. The MIA FORA NGS HLA typing software provides the sequence of the relevant HLA genes and phase information to achieve high resolution HLA typing.
REAGENTS A. Identification
See tables in Reagents by Catalog Number section for complete listing of products and catalog numbers.
B. Warnings and Cautions 1. For Research Use only. Not for use in diagnostic procedures. 2. Separate labs or enclosed lab spaces should be designated for Pre-PCR manipulations as well as for Post-PCR
manipulations. 3. Separate pipettes should be designated for Pre-PCR manipulations as well as for Post-PCR manipulations. 4. Biohazard: All biological and blood samples should be treated as potentially infectious. Use Universal Precautions when
handling. 5. Never pipette by mouth. Avoid contact of reagents and specimens with skin and mucous membranes. 6. Dispose of used materials in accordance with the Institution’s and/or local regulations for disposal of potential bio-hazardous
materials. 7. PCR technology is susceptible to contamination, especially from its own product. Aerosols of PCR amplicons that are
generated during the post-PCR steps are a frequent source of contamination. Thus care should be taken to prevent excessive splashing and generation of aerosols. Standard PCR laboratory measures that include wiping of work surfaces with freshly prepared 10% bleach before processing or preparing PCR samples, use of ultraviolet (UV) light in hoods or biosafety cabinets in between use, space and time separation of pre- and post-PCR activities, use of aliquoted PCR reagents, use of positive and negative controls, etc. should also be followed during the use of the kit. Use of consistent, careful technique coupled with liberal incorporation and monitoring of controls will ensure a vigilant, proactive approach to control and monitoring of PCR contamination.
8. Laboratories should validate their own cleaning procedures. 9. Contamination of reagents or specimens may cause erroneous results; therefore, care should be taken to avoid
contaminating this product during use. Do not use contaminated reagents. 10. Use the kit liquids as supplied. Dilution or alteration may generate erroneous results. Do not mix reagents between different
lots. 11. Do not use leaking or unlabeled vials. 12. Previously frozen samples or reagents should be thoroughly mixed and then centrifuged after thawing prior to testing. Avoid
generating foam and bubbles in the samples. 13. Keep all enzymes and master mixes on ice or cryo block (2 - 8°C) when thawing. 14. Ensure proper sample tube sealing prior to amplification to prevent evaporation. 15. Due to inherent differences in the mechanisms of thermal cycler performance, variation in results can occur when set
thermal profiles are transferred between different makes and models of thermal cycler instruments. In some cases, reaction specificity and sensitivity can be compromised, leading to the false interpretation and reporting of data. Alternate thermal cyclers and profiles must be validated by the user.
16. Incubation times or temperatures other than those specified may give erroneous results.
Page 4 of 14 LC1618RUO.3 (11/16) Copyright © 2015, Immucor Transplant Diagnostics, Inc. All rights reserved.
17. Deviation from the recommended directions for use may result in less than optimal product performance. Depending upon
the nature and severity of the deviation assay failure (individual sample as well as run failures) and/or erroneous results may occur. For example we have determined that use of insufficient/inactive bead clean up in the assay may result in high incidence of index adaptor failure calls.
18. It is recommended to perform gel electrophoresis for the analysis of HLA gene amplification products by size. PCR products should be visualized with ethidium bromide or gel red; other dyes may show weak bands.
19. Magnetic beads are used in several steps of the protocol. It is important to remove ethanol before proceeding to the elution step without allowing the beads to over dry. The surface of the magnetic beads should look glassy with no pools of liquid visible. The appropriate drying time may be determined empirically in each laboratory environment (approximately 8-10 minutes).
20. Use freshly diluted 80% ethanol for each bead clean. 21. After each bead clean there is a safe stopping point during which the samples or library can be stored at -20°C for up to 4
days. 22. Protect PicoGreen® plates from light to avoid bleaching. 23. It is critical that the fragmentation reaction not exceed 20 minutes and that bead clean be performed immediately to ensure
correct fragment size range. 24. The A-tailed plate must proceed directly to the adaptor ligation step. 25. When preparing the index adaptor ligation plate, use fresh gloves while handling the adaptor plate. Carefully remove the
plate seal. Verify that all wells in columns 1, 2, and 3 contain about 5 µL of solution. 26. The amplified library should be purified within 1 hour of amplification. 27. The library post-amplification steps should be performed in a sequencing room or in an AirClean PCR box to avoid
contamination of index-adaptor ligated DNA with final products that contain the Illumina cluster sequences. 28. Set-up for library quantification by qPCR or Qubit must be done in a PCR hood and with fresh dilution buffer for qPCR to
avoid contamination. 29. Perform sample denaturation with fresh 0.2N sodium hydroxide 30. Perform all sequencer post-run and maintenance washes and regular cleaning.
C. Storage Instructions 1. Store MIA FORA NGS HLA typing kit below -20ºC in a manual defrost freezer. 2. Do not use components past their expiration date. 3. Store magnetic beads at 2 to 8°C.
D. Purification or Treatment Required for Use See “Specimen Collection and Preparation.”
E. Instability Indications 1. If salts have precipitated out of solution during shipping or storage, re-solubilize completely prior to use by vortexing at room
temperature (18 to 30°C).
INSTRUMENT REQUIREMENTS 1. Thermal Cycler equipped with a heated lid, adjustable ramp times, and a minimal thermal range of 2°C to100 ° C and accuracy of at
least +/- 0.5°C. Conditions for thermal cyclers may need to be altered in order to optimize the profiles. The Veriti thermal cycler from Applied Biosystems, when run in the default mode with the ramp rate of (3.9ºC/sec), has been validated.
2. Appropriate Fluorescent plate reader with excitation filter ~ 485 nm and emission filter ~535 nm for measuring DNA concentration such as Victor X2, X3 has been validated.
3. Appropriate method/apparatus for isolation and purification of DNA fragments of about 400-500 base pairs in size. One such size selection apparatus Pippin Prep
TM instrument has been validated.
4. Optional Liquid handling system for semi-automated library construction. One such system Biomek4000 has been validated. 5. Appropriate method/apparatus for library quantification such as qPCR or Qubit. 6. Illumina sequencing has been validated. 7. MIA FORA NGS Server and Software: Immucor Part Number SR-790-00017.
SPECIMEN COLLECTION AND PREPARATION Human genomic DNA can be purified from Whole blood and Buffy coats using a validated method that meets the criteria below. DNA
extracted from blood preserved in EDTA have been tested and shown to yield expected performance in this assay. DNA extracted from blood preserved in heparin cannot be used in this assay.
The isolated DNA should be in 10 mM Tris-HCl, pH 8.0-9.0, or in nuclease free water. If a chelating agent such as EDTA is present, the final concentration of the chelating agent should not exceed 0.5 mM.
Final DNA concentration should be 5 to15 ng/µL.
Absorbance measurements of the DNA sample at 260 and 280nm should give a ratio of 1.65 to 2.0.
DNA can be used immediately after isolation or stored at –20ºC for up to 1 year. Repeated freeze/thawing should be avoided since this can result in DNA degradation.
At least 50% of genomic DNA samples must have fragments greater than 10 kb for successful long range PCR amplification.

B. DNA Amplification (PCR)
PCR Set-up 1. Fill out Sample Barcode File (a Windows Comma Separated CSV file) with sample names and barcode assignments as shown
in Figure 1.
Figure 1. Sample Bar Code File Example
2. Generate a project in the MIA FORA software after creating a sample barcode file with the sample names and barcodes. This project name is needed for the sequencer run name.
3. Label three hard shell semi-skirted 96-well PCR plates. 4. Prepare a sample plate with 100 µL of genomic DNA per well for each sample at a concentration of 5-15 ng/µL diluted in
nuclease free water. Sample plate should be arranged in columns 1, 2, and 3 of a 96 well plate as shown in the sample plate in Figure 2. Well A1
should be the 10mM Tris-HCl pH 8.0 negative control (NTC) containing no DNA, followed by sample 1 in B1, sample 2 in C1, and continue with up to sample 23 in H3 (Figure 2, SAMPLE PLATE).
5. Thaw the PCR master mixes (P1-P9), mix by inversion or briefly vortex and spin down. 6. Centrifuge the sample plate from step 4 in a centrifuge with a plate holder for 2 min, to ensure genomic DNA is at the bottom of
the well. 7. Dispense 15 µL of PCR mixes P1-P9 into columns 1-9 of each of the three hard shell semi-skirted 96-well PCR plates so that
each well of a column has the same PCR mix (Figure 2). 8. Dispense carefully to avoid bubbles in the PCR master mix. 9. Dispense the samples from the sample plate with a multichannel pipette as follows (Figure 2):
Column 1 from sample plate: 10µL of NTC and samples 1-7 in column 1 (A1-H1) into each of the nine columns of PCR Plate1. Column 1 from sample plate: 10µL of samples 8-15 in-column 2 (A2-H2) into each of the nine columns of PCR Plate 2. Column 1 from sample plate: 10µL of samples 16-23 in column 3 (A3-H3) into each of the nine columns of PCR Plate 3. NOTE: samples must be mixed gently to avoid bubbles in PCR master mix as shown in the Figure 2.
10. Seal PCR plates with Adhesive PCR film. Briefly centrifuge PCR plates, place into 3 separate thermal cyclers, and run the MIA FORA HLA_PCR program using heated lid setting, See Table 1.
SAFE STOPPING POINT

3. Transfer the tube to magnetic rack until the solution is clear. Remove and discard supernatant. 4. While still on the magnet, add 1 mL of 80% ethanol and incubate for 30 seconds. Remove the 80% ethanol without
disturbing the bound beads. 5. Repeat ethanol wash (step4) for a total of 2 washes. Remove as much of ethanol as possible from the tube. 6. Remove the tube from the magnetic rack and allow beads to air dry for approximately 5-10 minutes until the pellet of
magnetic beads has a glassy appearance. 7. Resuspend beads in 63 µL of room temperature 10mMTris-HCl pH8.0. Vortex and incubate 5 minutes. 8. Place the tube on the magnet until the solution is clear, and transfer 60 µL of eluate that contains cleaned adaptor ligated
samples into a clean microcentrifuge tube.
SAFE STOPPING POINT Pooled and Cleaned adaptor ligated samples (Library) can be stored at -20°C until ready to perform Size Selection for up to 4 days.
f. .Size Selection and Amplification of Size Selected Library (Pippin Prep)
NOTE: The amplified library should be purified within 1 hour of amplification.
1. Perform an appropriate size selection method on the library preparation to isolate fragments of approximately 400-500 base pairs. Follow the instruction manual of the product if not using Pippin Prep.
2. Mix 30 µL of Library with 10µL of appropriate marker and load into one lane of Pippin cassette. 3. Create and run a program to select Library with fragment size between 400-500bp. 4. Thaw Amplification modules from Library preparation kit tube 19, 20, 21 and assemble reaction in a 0.2 mL PCR strip
tube as follows:
Page 11 of 14 LC1618RUO.3 (11/16) Copyright © 2015, Immucor Transplant Diagnostics, Inc. All rights reserved.

E. Sequencing Preparation for MiSeq®
NOTE: Open and handle all Post-Amplification steps in a designated section of the laboratory, and preferably in a PCR safe hood to prevent contamination of work surfaces and sequencing reagents.
1. Transfer 50uL amplified Library into a microcentrifuge tube. Add 50µL of room temperature magnetic beads to the Library. Mix thoroughly and incubate for 10 minutes.
2. After 10minutes, place the tube in magnetic tube holder until solution is clear, about 5-8min. Remove and discard supernatant.
3. While still on the magnet, add 200 µL of 80% ethanol and incubate for 30 seconds. Remove the 80% ethanol without disturbing the bound beads.
4. Repeat ethanol wash (step3) for a total of 2 washes. Remove as much of ethanol as possible from the tube. 5. Remove the tube from the magnetic rack and allow beads to air dry for 5 - 10 minutes until the pellet of magnetic beads has
a glassy appearance. 6. Resuspend beads in 17 µL of room temperature 10mMTris-HCl pH8.0. Vortex and incubate 5 minutes. 7. Place the tube on the magnet until the solution is clear, and transfer 15 µL of eluate that contains cleaned, amplified
sequencing library into a clean microcentrifuge tube.
SAFE STOPPING POINT Eluted samples may be stored at -20ºC for up to 4 days.
8. Determine the concentration of Library using methods that accurately measure DNA concentration. Immucor recommends either the qPCR or Qubit methods to estimate Library concentration.
9. Due to the nature of the sequencer, sequencing library concentration should preferably be higher than 10 nM. The size distribution of the library can be determined by using agarose gel electrophoresis or any capillary electrophoresis system to verify the size of the resulting libraries.
10. Dilute the library to 4nM and then prepare an 8pM (if used Qubit) or 12 pM (if used qPCR) final denatured library for the MiSeq® and 1.3pM (Qubit) final denatured library for the MiniSeq ®. The library can be spiked with 5% PhiX control if desired.
11. Load denatured library on cassette and run on the sequencer. 12. Follow Illumina instructions for sequencing of the. Make sure that the file name in the sample sheet matches the project
name generated during Long Range PCR set up.
F. Data Analysis
The fastq files generated by the MiSeq® instrument should be analyzed with the MIA FORA software to generate the HLA typing. The sample sheet with the sample names and barcodes, and the corresponding fastq files should be loaded into the project file of the MIA FORA software. For use of the MIA FORA software, follow the Software User Guide.
RESULTS
1. PCR amplification: Agarose gel analysis should show no product in the negative (NTC) control for the run to be valid. Agarose gel of amplified products can show variations in size based on differences in intronic sequences. Refer to Table 2 for approximate size of bands.
2. Library Preparation: Library Kit should generate a library when the input DNA level in SironaQuant is between 0.0009 and 0.0035 pmol. The final concentration of the library should be at least 10 nM, and should be accurately quantified before sequencing. Libraries should be diluted to 4nM prior to denaturation. Clustering on MiSeq® and MiniSeq® kits can vary depending on accuracy of quantification. Typically, cluster densities of 8-12pM libraries should range from 600-800 K/mm
2 on the MiSeq® and 160-220 K/mm
2 on the MiniSeq Care must be taken to
accurately quantify the library. All post adaptor ligated products must be contained to a PCR hood or designated area and fresh dilution reagents must be prepared to prevent contamination.
3. HLA Typing is generated by the MIA FORA NGS Software and is provided in a report. Follow MIA FORA Software User Guide for HLA typing data analysis.
QUALITY CONTROL It is required that one negative control and an optional known control be run with each test, such as a water blank and a previously typed sample respectively. Extreme care must be used when removing plate seals and the plates must be spun down prior to opening. New plate seals must be used at every step where the plates need to be sealed. The used pipette tips should be placed into appropriate containers and discarded. PCR set up must be performed in a Pre-PCR room separate from where amplified products are handled. All genomic DNA must be

diluted in nuclease-free water. After the DNA size selection and amplification, the amplified library must be handled in a separate area, preferably a PCR hood, and handled with a separate set of pipettes. Care should be taken to not contaminate the work areas with amplified libraries. The assay should be run as recommended in this product insert as well as performed with any other quality control procedures that are in accordance with local, state, federal and/or accreditation agencies requirements.
LIMITATIONS OF THE PROCEDURE 1. The PCR and assay described in this product insert require precisely controlled conditions. Deviations from validated parameters
may lead to product failure. 2. If at least 50% of initial DNA fragments are less than10 kb, sufficient quantity of long range PCR product may not be generated. 3. If the final library concentration is below 10 nM, accurate sequencing results may not be generated. 4. Ambiguities in the 4
th field will be observed due to lack of coverage in intron region.
5. Additives in the PCR mix may interfere with commonly used non-toxic ethidium bromide alternatives used in agarose gel electrophoresis and may lead to lower band intensity.
6. SYBR® green stained agarose gels do not work with the PCR products. Ethidium bromide or GelRed™ should be used for visualization of PCR products.
7. The DPB1 primer does not amplify exon 1 or exon 5. Therefore any known polymorphisms in these exons will not be sequenced, and will be listed as ambiguities in the report.
8. The lack of genomic reference sequences for DPB1 and the low levels of polymorphism in intron 2 (between exon 2 and 3) make it challenging to perform phasing analysis for heterozygous samples. Therefore there may be a genotype ambiguity that cannot be resolved.
9. The forward primers for DPB1 overlap with the first few bases on exon2. Therefore polymorphisms in those sequences will not be identified by sequencing.
10. The DRB loci are amplified as two fragments – one that amplifies exon 1 and another that amplifies exons 2 to 6. Intron 1 is not amplified in its entirety. Therefore the phasing of the entire locus is not possible for DRB1/3/4/5 and any polymorphisms present in Intron 1 will result in 4th field ambiguities.
11. The reverse primer for DRB exons 2 to 6 overlaps the 3’end of the exon 6, therefore polymorphisms in those sequences will not be determined by sequencing.
12. In most cases, the amplification products of exon 1 of DRB1,3,4,5 map poorly to exon 1 of the known reference sequences of DRB5; thus contig for exon 1 will not likely be generated for DRB5. Since there are no known exon 1 polymorphisms for DRB5, it does not lead to any ambiguity in the HLA typing for DRB5.
13. Due to the complex nature of HLA typing, qualified personnel should review data interpretation and typing assignments.
