体外活性 | Sulfo-NHS-SS-biotin 是一种带负电荷的试剂,不能穿透细胞膜。它与一级胺(NH2),如赖氨酸侧链或多肽的氨基末端发生反应[1]。在单层培养的细胞中,使用Sulfo-NHS-SS-biotin(1 mg/ml;15分钟)进行处理,并用冰冷PBS洗涤。生物素化反应通过在PBS中加入100 mM甘氨酸来终止。随后用PBS洗涤后,利用含有蛋白酶抑制剂的RIPA缓冲液制备细胞提取物[2]。 |
别名 | Sulfosuccinimidyl 3-[[2-(biotinamido)ethyl]dithio]propionate, Sulfo-NThiol-SS-biotin, Sulfo-NHS-SS-Biotin (sodium), Sulfo-NHS-SS-Biotin |
