简介
三(2-羧基乙基)膦盐酸盐(TCEP盐酸盐)是一种新型的巯基化DNA的还原剂和去保护剂。巯基化DNA末端硫原子在溶液中趋向于形成二聚体,特别是在存在氧气的情况下。这种二聚化大大降低了一些偶联反应实验(如DNA在生物感应器中的固定)的效率;而在DNA溶液中加入三(2-羧基乙基)膦盐酸盐(TCEP盐酸盐),反应一段时间后除去,就可以降低DNA的二聚化。
用途
三(2-羰基乙基)磷盐酸盐为有机磷化合物,可用作水溶性试剂,用于二硫化物的选择性还原;在质谱应用中比 DTT 更稳定;也可用于在水中进行的二硫化物选择性还原。
生物活性
TCEP hydrochloride (Tris(2-carboxyethyl)phosphine hydrochloride) 是一种非硫醇还原剂,比其他化学还原剂更稳定并且产生更快的 S-S 还原反应。TCEP hydrochloride 是一种三烷基膦,可选择性地减少蛋白质的分解,而不会改变其性质或与反应混合物中的硫醇导向剂发生相互作用。TCEP hydrochloride 还是 DNA/AuNP 化学中常用的还原剂。
体外研究
TCEP hydrochloride has been introduced which oers the prospect of serving as an alternative to the more commonly employed DTT in the NF-κB-DNA binding reactions in vitro, using recombinant p50 protein and a 32 P-labelled κB oligonucleotide. DTT promotes NF-κB-DNA binding in concentrations from 0.25 to 2.6 mM in binding reactions. However, in the presence of 0.25 mM DTT, inhibition of NF-κB binding is seen only at Hg 2+ concentrations greater than 100 μM and results are highly variable. In contrast, TCEP hydrochloride promotes NF-κB-DNA binding in a dose-related manner in concentrations from 0.25 to 6 mM. In the presence of even 6 mM TCEP hydrochloride, Hg 2+ prevents NF-κB-DNA binding at concentrations as low as 20 μM in binding reactions.
The human lactoferrin (hLF) peptide is dissolved in phosphate buffer to a concentration of 0.1 mm. Reduction of the disulfide bonds is obtained by adding a 30-fold molar excess of TCEP hydrochloride with subsequent incubation for 2 h at 37 ℃.
