Gene Information

Application

Reagent for the covalent modification of cysteine residues in proteins.
N-Ethylmaleimide (NEM) has been used:
  • to prepare NEM-modified myosin beads
  • to block unmodified free thiols in samples
  • as a supplement in IP lysis/wash buffer for in vitro SUMOylation assay

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.
