Thermo Scientific™ Pierce™ NEM (N-ethylmaleimide)

Thermo Scientific Pierce N-Ethylmaleimide (NEM) is a small compound that forms stable, covalent thioether bonds with sulfhydryls (e.g., reduced cysteines), enabling them to be permanently blocked to prevent disulfide bond formation.

Features

• Permanently block sulfhydryls to prevent disulfide bond formation.
• Monitor the reaction by measuring the decrease in absorbance at 300nm
• Block sulfhydryl-containing reagents that interfere in enzyme assays
