Comparison of immunological and enzymatic properties of human urinary and pancreatic kallikrein

Abstract

Human urinary and human pancreatic kallikreins were compared by radioimmunoassay, immunoelectrophoresis, by their enzymatic activity using the substrate Ac-Phe-Arg-OEt and by their biological activity employing the dog blood pressure assay. The only significant difference observed was a higher anodal mobility of the urinary kallikrein under the conditions of immunoelectrophoresis.
