Supplemental figure 2. Effect of the ALPL specific inhibitor on recombinant proteins
The effect of the ALPL specific inhibitor, levamisole, was examined on phosphatase activity from recombinant ALPL, ALPI, ALPP, and ALPPL2 (A), and recombinant LPP1 and LPP3 (B). Dephosphorylation activity was normalized by each no inhibitor control. The data are shown as the means of duplicates with error bars to the minimum and maximum values (n = 2).

The ALPL specific inhibitor, levamisole, was tested for CS-0777-P phosphatase activity in human kidney homogenates of five human specimens. Dephosphorylation activity was normalized by each no inhibitor control. The data are shown as the means of duplicates with error bars to the minimum and maximum values (n = 2).

Recombinant lysates were immunodepleted with an anti-human ALPL antibody or normal mouse IgG, and tested for CS-0777-P phosphatase activity. The activity was normalized by the activity of each recombinants immunodepleted with normal mouse IgG. The data are shown as the average of duplicates with error bars to the minimum and maximum values (n = 2).

The ALPL specific inhibitor, levamisole, was tested for CS-0777-P phosphatase activity in human tissues (kidney homogenate, liver homogenate, lung S9 fraction, and small intestine S9 fraction). Dephosphorylation activity was normalized by each no inhibitor control. The data are shown as the means of duplicates with error bars to the minimum and maximum values (n = 2).
