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.
用细胞化学方法，借助过氧化物酶，在电子显微镜下研究了伴刀豆球蛋白A在大鼠肝细胞内的结合位点。伴刀豆球蛋白A仅在预先切割的细胞中渗透，这种凝集素的结合位点位于内质网和高尔基体上。结果表明，这些位点至少部分地与肝细胞合成和分泌的血浆糖蛋白有关。
