Invitrogen™ Human Activated Protein C, Native Protein

Description

Activated Protein C (human) Native Protein, RP-43095, from Invitrogen.

Protein C is a vitamin K-dependent plasma glycoprotein that is cleaved to its activated form by the thrombin-thrombomodulin complex. Protein C in its activated form contains a serine protease domain and functions in degradation of the activated forms of coagulation factors V and VIII. Protein C is a vitamin K-dependent serine protease produced in the liver and made up of 2 polypeptide chains. The 62 kDa proenzyme is activated by thrombin bound to an endothelial surface receptor and the active enzyme cleaves factor Va and VIIIa and thus inhibits blood coagulation. The molecular weight of the active enzyme is 55 kDa and the normal concentrations in human plasma is approximately 1-3ng/mL because of the very fast turnover, the proenzyme concentration is approximately 3ug/mL. Mutations in the Protein C gene have been associated with thrombophilia due to protein C deficiency, neonatal purpura fulminans, and recurrent venous thrombosis. RP-43095 contains native human Activated Protein C protein. RP-43095 may be used as a positive control in many immunological assays. The RP-43095 protein molecular weight is ∽56.2 kDa. The product is of human blood/plasma origin. Although the starting material was tested prior to initiation of the manufacturing process, and was found negative or nonreactive for anti-HIV-1/2, HIV-1 antigen(s), HBsAg, STS, anti-HCV, anti-HBcore and anti-HTLV I & II, extreme caution should be used when handling this material as there is a margin of error in all tests. This product is to be used for IN VITRO research purposes only, and is not intended for clinical or diagnostic use!
