Background

Tris (2-carboxyethyl) phosphine hydrochloride (TCEP HCL) is a water soluble strong reducing agent that cleave disulfide bonds. It is a non-thiol and non-volatile solid. It can be utizlied as catalyst for the reduction of sulfonyl chlorides, N-oxides, sulfoxides and azides.

In measuring DHA (Dehydroascorbic acid) content in multiple tissues and plasma of 6-weeks-old mice, 35 mM TCEP HCL fully reduced DHA to AA (Ascorbic acid) after 2 hours on ice in a 5% solution of metaphosphoric acid containing 1 mM ethylenediaminetetraacetic acid (EDTA) at pH 1.5 [1]. In Aspergillus saitoi protease type XIII and porcine pepsin, TCEP can also be used in proteolysis and hydrogen/deuterium exchange [2].
