| Popis: | Human duodenal juices collected during tube instillation of raw soybean extract into the duodenum contained free trypsin and free Kunitz soybean trypsin inhibitor (KTI) in the simultaneous presence of trypsin-KTI complexes. It has previously been suggested that this KTI-non-inhibitable trypsin has a general resistance to serine protease inhibitors. Four different trypsin forms have been found and partly characterized by sodium dodecyl sulphate-polyacrylamide gel electrophoresis and isoelectric focusing followed by Western immunoblotting or enzyme staining. In addition, crossed immunoelectrophoresis and affinity chromatography with antibody-coupled gels have been used for identification of free and inhibitor-complexed trypsin. |
