生化/生理作用

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。

其他说明

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。

外形

Contains phosphate buffer salts and sodium chloride

分析说明

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。

Neovascular retinopathies are major causes of vision loss; yet treatments to prevent the condition are inadequate. The role of regulatory T cells in neovascular retinopathy is unknown. Here we show that in retinopathy regulatory T cells are transiently increased in

Retinopathy of prematurity (ROP), the most common cause of blindness in premature infants, has long been associated with inner retinal alterations. However, recent studies reveal outer retinal dysfunctions in patients formerly afflicted with ROP. We have recently demonstrated that choroidal
