产品说明

应用

General Western Blot Protocol:

  • Glycoprotein sample size: 500ng
  • Lectin Concentration: 0.1ug/ml

  1. Load samples at 500 ng of glycoprotein per lane
  2. Run 4-20% Bis-Tris SDS page gel
  3. Transfer gel to a PVDF membrane
  4. Block membrane for 1 hr at RT with RIPA buffer (R0278 Sigma)
  5. Incubate HRP lectin at 0.1ug/ml with RIPA buffer for 2 hours at RT
  6. Wash membrane 5 x 5 minutes with 25ml RIPA buffer
  7. Detect using chemiluminescent substrate (CPS1-120)

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。

单位定义

One unit will form 1 mg purpurogallin in 20 sec from pyrogallol at pH 6.0 at 20 ℃.

外形

Contains sodium citrate buffer salts and calcium chloride

制备说明

Prepared from peroxidase type VI using a modification of the method of O′Sullivan, et al. Repurified by affinity chromatography after conjugation.

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。
