The carbohydrate compounds of the mucus of flask cells in the kidney of claw-frogs (Xenopus laevis) were studied by gold marked lectins (WGA, RCA, L, LCA, HPA, PNA). We used a post-embedding technique. Seminthin or ultrathin sections of Lowieryl K H M-embedded kidney tissue were incubated. For light microscopy, a gold-silver technique was used. The mucus of the flask cells reacted strongly with WGA, RCA L and HPA, whereas LCA and PNA showed no binding. The Golgi apparatus and small cytoplasmatic vesicles reacted also positively with WGA, RCA L and HPA. The autoradiographically detected secretion routes of the glycosaminoglycan-rich secretion of flask cells are also demonstrable by lectins.
