近 2 0年来凝集素在生物学方面的应用研究发展尤为迅速 ,它最大的特点在于其能够识别糖和糖类 ,每一种凝集素具有对某一种特殊的碳水化合物有专一结合的能力 [1 ] ,凝集素受体是指能与相应凝集素特异结合的糖复合物 (糖蛋白 ,糖脂和蛋白聚糖 ) ,它在细胞的多种功能中起主要作用 Lectin nearly 20 years in the biological aspects of the application of research and development is particularly rapid development, its greatest feature is that it can recognize sugar and carbohydrates, each of the lectins have a specific combination of specific carbohydrate capacity [1] Lectin receptors refer to glycoconjugates (glycoproteins, glycolipids and proteoglycans) that specifically bind to the corresponding lectins and play a major role in various cellular functions
