NHS-SS-biotin [Succinimidyl-2-(biotinamido)-ethyl-1,3-dithiopropionate]是一个长链裂解的胺反应性生物素化试剂,由于结构中横桥的存在,它具有24.3 A长度的间隔臂。长间隔臂增加了共价修饰分子与双环生物素环之间的长度,从而增强分子与亲和素或链亲和素探针的结合能力。NHS-SS-biotin的NHS酯基与蛋白和其它分子的胺基反应形成酰胺键,并释放sulfo-NHS。NHS-SS-Biotin是水不溶性的分子,在加入反应性水溶液之前需要先溶于有机溶剂中。

• Protein labeling—biotinylate antibodies or other proteins for detection or purification using streptavidin probes or resins
• Intracellular labeling—membrane-permeable, can be used to label inside cells
• Amine-reactive—reacts with primary amines (-NH2), such as the side-chain of lysines (K) or the N-terminal-amine
• Cleavable—disulfide bond in spacer arm allows the biotin label to be removed using reducing agents such as DTT
• Solubility—water insoluble, must be dissolved in DMSO or DMF before further dilution in aqueous buffers
• Medium length—spacer arm is 24.3 angstroms; it consists of the native biotin valeric acid group extended by a 7-atom chain

Preparation method |
Soluble in DMSO or DMF. |
Reaction Conditions |
1.5 mg/ml, 4 ℃ for 1 h |
Applications |
Neurons were washed with the artificial cerebrospinal fluid(ACSF) at 37 ℃, and incubated with 1.5 ml of 1.5 mg/ml NHS-SS-biotin with gentle shaking at 4 ℃ for 1 h. After washing, neurons were switched to the neuronal culture medium and incubated at 37 ℃. At indicated times of incubation, neurons were cooled to 4 ℃ and un-endocytosed surface biotin was cleaved by incubating in the glutathione cleavage buffer (50 mM glutathione, 75 mM NaCl, 10 mM EDTA, 1% BSA, and 0.075 N NaOH). Neurons were lysed in the modified RIPA buffer (50 mM Tris–HCl, 150 mM NaCl, 1% NP-40, 0.5% sodium deoxylate, 1 mM EDTA, and protease inhibitors). Lysates were cleared by centrifugation at 10,000g for 10 min at 4 ℃ and incubated at 4 ℃ over-night with 70 μl of 50% streptavidin beads. Endocytosis of ErbB proteins was assayed using cleavable biotin. Bead-associated proteins were subjected to Western blot analysis. |
