Effect of Cp40 on NHP serum-mediated CDC. PI-positive dead cells were detected by FACS after incubation of iPECs with 20% rhesus (A) or cynomolgus monkey (B) serum that had been pretreated with various doses of Cp40 (final concentrations from 1.25 to 1280 μg/ml). iPECs incubated with 20% heat-inactivated normal monkey serum (HINMS) were used as negative controls. Data shown are means ± SEM (n = 3).
