Immunogenicity of guinea-pig submandibular and coagulating gland kininogenases

The antigenic relationship between submandibular and coagulating gland kininogenases of the guinea-pig has been examined using Ouchterlony double diffusion, crossed and rocket immunoelectrophoresis and immunofluorescent techniques. The evidence suggests a partial immunological identity between submandibular and coagulating gland kininogenases of the guinea-pig. In this respect these enzymes seem to differ from the glandular kallikreins of other species (porcine, human and rat) which apparently share a complete immunological identity.
