凝集素是存在于动物和植物中的一种蛋白质,它可以特异性地与某种糖基结合并发生凝集反应。麦芽凝集素(WGA)是一种可与 N-乙酰葡萄糖胺或唾液酸结合的凝集素。近年来发现在体内许多细胞表面有 WGA 的受体,并发现该受体具有重要意义。上海第二医科大学王一飞(Wang Yifei)等从80年代初以来运用凝集素技术对人类精子膜 WGA 受体的性质、分布、发育过程以及与男性生育力和不育的关系进行了系统研究,发现该受体与男性生育力密切相关。运用比浊法(一种半定量方法)对110例正常生 Lectins are found in animals and plants in a protein that can specifically bind to a certain sugar and agglutination. Maltogenic Agglutinin (WGA) is a lectin that binds to N-acetylglucosamine or sialic acid. In recent years, it has been found that there are WGA receptors on the surface of many cells in vivo and found to be of great importance. Since the early 1980s, Shanghai Second Medical University Wang Yifei et al. Have systematically studied the properties, distribution, developmental processes and relationships with male fertility and infertility of human WGA receptors using lectin technology. This receptor is closely related to male fertility. Using turbidimetry (a semi-quantitative method) on 110 cases of normal students
