N-Ethylmaleimide Chemical Properties,Uses,Production
Chemical Properties
White solid
Uses
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.
Hazard
Lachrymator when liquid, a strong irritant.
Safety Profile
Poison by intraperitoneal route. Human mutation data reported. Vapors are hlghly irritating. When heated to decomposition it emits toxic fumes of NOx.
