Application
Reagent for the covalent modification of cysteine residues in proteins.
Biochem/physiol Actions
Augments currents from native M-channels in sympathetic neurons and acts as an opener for KCNQ2, KCNQ4 and KCNQ5 channels.
Sulfhydryl alkylating agent that inactivates NADP-dependent isocitrate dehydrogenase and many endonucleases.

E817900 

Reagent for the covalent modification of cysteine residues in proteins.NEM gives a clear solution in ethanol at 50 mg/ml. NEM dissolves in water (>50 mg in 4 ml); however, aqueous solutions are unstable. The rate of hydrolysis is pseudo-first order and si
