Description

Applications
Cysteine alkylating agent 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.

Solubility
Soluble in ethanol, water, chloroform, methanol and toluene.

Notes
Light sensitive. Store in cool place. Incompatible with strong oxidizing agents, strong acids and strong bases.
