化合物Sulfo-NHS-SS-Biotin sodium T19061

Product Introduction
Bioactivity


英文名: Sulfo-NHS-SS-Biotin sodium

描述: Sulfo-NHS-SS-Biotin sodium (Sulfosuccinimidyl 3-[[2-(biotinamido)ethyl]dithio]propionate) 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 sodium 可用于细胞表面蛋白 (cell-surface protein) 的标记和纯化。

体外活性: Sulfo-NHS-SS-biotin 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[1]. 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 [2].

存储条件: store at low temperature,keep away from direct sunlightPowder: -20°C for 3 years | In solvent: -80°C for 1 year

溶解度: H2O : 180 mg/mL (296.7 mM)
DMSO : 100 mg/mL (164.8 mM)
