Description
OverviewWater-soluble reagent useful for the reduction of native disulfide bonds in proteins. Considered to be a superior reducing agent to DTT. Shown to reduce accessible disulfide bonds in immunoglobulin and trypsinogen under non-denaturing conditions 5 to 7 times faster than DTT at pH 7. The relatively less accessible disulfide bond in α-chymotrypsinogen A was reduced 2.3 times faster at with BMS than with DTT at pH 7.0.
