Pyruvate kinase isozyme patterns of human neoplastic, fetal and adult tissues

  • 33 Accesses


A method of starch gel electrophoresis is described which enables detection of 6 isozymes of human pyruvate kinase (PK,E.C. Comparing the PK-isozyme patterns of 53 diverse human tumors with those of normal adult and fetal organ tissues, it was found that the isozyme PK I is predominant in all malignant tumors as well as in almost all fetal organs.


Es wird eine Methode der Stärkegelelektrophorese beschrieben, die die Darstellung von 6 Isoenzymen menschlicher Pyruvatkinase (PK,E.C. ermöglicht. Ein Vergleich der PK-Isoenzymmuster von 53 verschiedenen menschlichen Tumoren mit denen von normalen adulten und fetalen Organgeweben zeigt das Vorherrschen des Isoenzyms PKI in allen malignen Tumoren und fast allen fetalen Organen.
