[Histochemical evidence of aminotransferases. IV. Histochemical and electrophoretical investigation of aminotransferases in rat organs (author's transl)].

The histochemical localization and isoenzyme profil of some aminotransferases in different organs of the rat has been studied. A positive histochemical reaction with unequal intensity, depending on the aminotransferase investigated, was been observed. The topochemical and cytochemical localization of the aminotransferases was typical for everyone organ. The studied aminotransferases possessed isoenzyme fractions with characteristic number, electrophoretic mobility and intensity in the different organs. The results were discussed in relation with substrate specifity of the aminotransferases.
