TCEP hydrochloride

CAS No. : 51805-45-9

MCE 站：TCEP hydrochloride

产品活性：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。

In Vitro: TCEP hydrochloride has been introduced which o?ers 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 ³²P-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 Hg²⁺ 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, Hg²⁺ 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 ℃.
