설명

일반 설명

A protective agent for SH groups.

Water-soluble protective reagent for sulfhydryl groups [absorbance (100 mM): ≤0.5 at 260 nm; ≤0.1 at 280 nm]. It is capable of maintaining monothiols completely in the reduced state and of reducing disulfides quantitatively. Since it readily permeates cell membranes, it can protect protein sulfhydryls and restore enzyme activity lost by oxidation.
