Abstract
The defect in the tapetum of beagles with an inherited tapetal abnormality may be due to the absence of both Zn and cysteine from the tapetal rods. This was demonstrated by direct measurement of Zn and cysteine and by histochemical localization of Zn. The latter method also indicated an interesting substructure in tapetal rods from normal beagles, in which Zn is apparently distributed in 2 concentric rings. The chemical changes involved in different methods of fixing this unique tissue were examined and correlated with the ultrastructure.This publication has 13 references indexed in Scilit:
