Application

Lectin from Bandeiraea simplicifolia (Griffonia simplicifolia) has been used:
  • for highlighting murine endothelial cells
  • to identify fetal capillaries in endothelial immunohistochemical staining, conjugated with biotin
  • to detect tumor total vessels

Biochem/physiol Actions

BS-I对末端α-D-半乳糖残基具有主要亲和力,对末端N-乙酰基-α-D-半乳糖胺残基具有二级亲和力。

Physical form

Contains sodium citrate

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最低浓度。

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-D-半乳糖残基具有独特的亲和力,而BSI-A4 具有血型A特异性,其对末端N-乙酰基-α-D-半乳糖胺残基具有主要亲和力。
