title: A monoclonal antibody recognizing an iscosapeptide sequence in the heavy chain of human factor XII inhibits surface-catalyzed activation.
abstract: A monoclonal antibody (mAb B7C9) to human factor XII was produced which blocked the surface mediated coagulant activity of factor XII but not the amidolysis of H-D-ProPheArg-pNA. The mAb epitope was localized to a 20 amino acid sequence of 2.5 kDa in the heavy chain of factor XII.
