植物凝集素是一类能凝集红细胞和其它细胞的旦白质,大多数为糖旦白,广泛存在于生物界中。由于它有一些重要的功能和特性,引起了学者们的极大兴趣。如有些凝集素能专一的凝集人类不同血型的红细胞,因而可用于鉴定血型和用于血型专一性化学基础的研究。有的凝集素可促进细胞有丝分裂的作用,因而可用于淋巴细胞的转化。在一些实验室中,凝集素已成为研究细胞表面的工具。由于凝集素能专一地结合糖,沉淀多 Plant lectins are a class of proteins that agglutinate red blood cells and other cells, most of which are glycoproteins, which are found extensively in the biological world. Because it has some important functions and characteristics, aroused great interest of scholars. For example, some lectins can specifically agglutinate human erythrocytes of different blood types and thus can be used to identify blood groups and to study blood-based chemical basis. Some lectins can promote cell mitosis, which can be used for lymphocyte transformation. In some laboratories, lectins have become tools for studying the cell surface. Because lectins can be combined with sugar, precipitation and more
