外切糖苷酶-
方法：通过蛋白酶消化提取细胞表面3H标记N糖链，结合外切糖苷酶处理，经序列凝集素亲和层析分析HL60细胞诱导分化后细胞表面N糖链结构。
Methods : 3H labeled N linked sugar chains were extracted from the surface of HL 60 cells using pronase digestion after induced differentiation of the cells , and the structure of N sugar chains were analyzed with serial lectin chromatography , combining with exoglycosidase treatment .
