Description

N-Ethylmaleimide is a protein thiol modifier which inhibits apoptotic DNA fragmentation. It is a sulfhydryl reagent and finds application in experimental biochemical studies as well as in enzymology. It is involved in the modification of cysteine residues in proteins and peptides. It acts as a Michael acceptor and reacts with nucelophiles like thiols. It is employed in the inhibition of Mg2+ dependent internucleosomal DNA fragmentation.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
