BIOPHEN Protein C 5 kit is for in vitro quantitative determination of Protein C activity on human citrated plasma. Protein C is a glycoprotein, vitamin K dependent, which inhibits coagulation. Protein C in plasma is measured following a specific activation with Protac (Agkistrodom Contortrix), an enzyme extracted from snake venom. Activated protein C hydrolysis the chromogenic substrate (SaPC-21) which release para-nitroaniline (pNA). The amount of pNA released (measured by absorbance at 405 nm) is directly proportional to the concentration of Protein C in the specimen.
