Overview

Purified from fresh frozen human plasma. Human Prekallikrein is a single chain gamma globulin glycoprotein that participates in the early phase of contact activation, kinin formation and fibrinolysis. Prekallikrein purity is determined by SDS-PAGE and shows no reduction upon incubation with 2-mercaptoethanol. Activity is determined via clotting assay.
Buffer composition = 4 mM Sodium Acetate-HCl/0.15 M NaCl/pH 5.3
Extinction Coefficient (1%) =11.7
Molecular Weight = 86,000 daltons
The above protein was purified from Human plasma units that test negative for antibodies to HBc, HCV, HIV 1/2, HTLV-I/II, and non reactive for HBsAg, HIV-1 RNA, HCV RNA, HBV DNA and Syphilis by FDA approved tests. Donors are screened for CJD.
