PC Antigen: Enzyme Immunoassay (EIA) PC Activity: A specific enzyme extracted from the venom of agkistrodon c. contortrix is used to activate PC in the patient sample. All other factors required for normal aPTT are supplied in the reagent. The activated protein C Inhibits factors V and VIII in the reagent and the resultantprolongation of the aPTT-based clotting time is proportionalto plasma PC activity
