Specificity
This antibody recognizes two variants of prekallikrein in human plasma, 88kDa and85kDa, and its activation products kallikrein, the complexes formed by kallikrein with itsendogenous inhibitors C1 inhibitor, alpha-2-macroglobulin and antithrombin III, and 45kDaprekallikrein/kallikrein fragments. It also recognizes prekallikrein and its activation products inchimpanzee, rhesus, and baboon plasmas. The epitope for this antibody is located on theprekallikrein/kallikrein heavy chain and is involved in the interaction between prekallikrein andfactor XIIa. This antibody inhibits prekallikrein activation in human and rhesus plasmas by ~60-80% and 55%, respectively. This antibody does not cross-react with tissue kallikrein.
