Preparation Note
Purified by affinity chromatography using the method of Hayes, C. E., and Goldstein, I. J., J. Biol. Chem., 249, 1904 (1974).
Analysis Note
凝集活性以 μg/mL表示，并且使用磷酸盐缓冲盐水（pH6.8）对1mg/mL溶液进行连续稀释液来测定，对于每种凝集素，所含有钙、镁和锰的浓度不同。该活性是在25℃孵育1小时后，对2％合适的红细胞悬浮液进行凝集所需的**浓度。
Other Notes
BS-I是一种四聚体凝集素，由两种类型的亚基A和B组成。存在由不同亚基组成的五种BS-I同工凝集素：BSI-B4、BSI-AB3、BSI-A2B2、BSI-A3B、以及BSI-A4。BSI-B4 是血型B特异的，其对末端α-
