[Intracellular localization of concanavalin A receptors in rat hepatocytes].
Intracellular binding sites of concanavalin A were studied in rat hepatocytes under electron microscopy with a cytochemical method using peroxidase. The penetration of concanavalin A occurs only in cells previously cut and the binding sites of this lectin are located on the endoplasmic reticulum and the Golgi apparatus. The results suggest that these sites are in relationship, at least in part, with the plasma glycoproteins synthesized and secreted by the hepatocytes.
