title: [Immunochemical, electrophoretic and enzymatic analysis of the pepsinogen-pepsin isoforms of human gastric mucosa and gastric tumors].
abstract: The obtained specific antiserum against the 1st isoform of pepsinogen of human gastric mucosa responds in immunodiffusion only to the 1st pepsinogen isoform but not to the IId and IIIth one. Human pepsinogen has no common antigenic determinant with pig pepsinogen. The methods of electrophoresis and immunodiffusion reveal the Ist, IId and IIIth isoforms of pepsinogen in human gastric tumors and their metastases, however, they do fail to show any enzymic activity.
