Development of a DPAP1-specific HTS assay.

<p><b>A.</b> Continuous assay. The assay was carried out in 384-well plates using 1% of parasite lysates. Substrate turnover was continuously measured for 5 min. JCP410 (10 µM) was used as a positive inhibition control. Z’ factor, S/N, and % CV of the negative control are shown. <b>B.</b> End-point assay for HTS. The reaction described in A was quenched after 10 min by addition of 0.5 M acetic acid. The final concentration of rhodamine product was quantified by fluorescence.
