特異性:Anti-Prekallikrein Heavy Chain [MurineMAb recognizes the heavy chain of human prekallikrein.] This antibody specifically recognizes in human plasma two variants (88 kDa and 85 kDa) of prekallikrein and its activation products kallikrein (88 kDa and 85 kDa), the complexes formed by kallikrein with its endogenous inhibitors C1 inhibitor, alpha-2-macroglobulin and antithrombin III, and 45 kDa prekallikrein/kallikrein fragment(s). It also recognizes prekallikrein and its activation products in chimpanzee, rhesus, and baboon plasmas. The epitope for this antibody, located on the prekallikrein/kallikrein heavy chain, is involved in the interaction between prekallikrein and factor XIIa. This antibody inhibits prekallikrein activation in human and rhesus plasmas by approximately 60-80% and 55%,respectively. This antibody does not cross-react with tissue kallikrein.
