简介
Sulfo-NHS-SS-生物素是一种可裂解试剂,可用于将生物素部分引入含有伯胺的蛋白质和细胞表面。 这种生物素化合物由于其带负电荷的水溶性磺酸盐基团是不透膜的。 该接头中的二硫键可以使用还原剂(如 DTT、BME 和 TCEP)裂解以去除生物素标记。
生物活性
Sulfo-NHS-SS-biotin 是一种长链可裂解和细胞无渗透的胺类活性生物素化 (biotinylation) 试剂。Sulfo-NHS-SS-biotin 可用于细胞表面蛋白 (cell-surface protein) 的标记和纯化。
靶点

IC50: cell-surface protein

体外研究

Sulfo-NHS-SS-biotin is a cell-surface-labeling reagent, it is a negatively charged reagent and does not permeate cell membranes. Sulfo-NHS-SS-biotin reacts with primary amines (NH2), such as lysine side-chains, or the amino-termini of polypeptides. Sulfo-NHS-SS-biotin has a sulfonate group and prevents it from permeating cell membranes. Thr group’s cleavable spacer arm enables initially biotinylated proteins to be released from streptavidin affinity columns. Sulfo-NHS-SS-biotin (1 mg/ml; 15 min) is applied in cells in monolayer culture (washed by ice-cold PBS). The biotinylation reactions are terminated with 100 mM glycine in PBS. After washing with PBS, cell extracts are prepared in RIPA buffer with protease inhibitor cocktail ( HY-K0010 ). Biotinylated membrane proteins are precipitated with streptavidin-sepharose and proteins are eluted with SDS sample buffer.
