[Immunochemical assessment of the antigenic relationship between the pancreatic kallikrein of rodents and carnivores].

Using quantitative and qualitative immunochemical methods, in combination with isoelectrical focusing, it was shown that antibodies to commercial kallikrein are involved into precipitation reaction with kallikrein in extracts from the pancreas of dogs, cats, guinea pigs, rats and mice. Complexes antigen--antibody exhibit similar physico-chemical properties; during isoelectric focusing, they are found in the same pH range as the immunoactive portion of commercial kallikrein. These data indicate antigenic similarity of pancreatic kallikrein in different mammalian species.
