Description
- Application: N-Ethylmaleimide (NEM) has been used:to prepare NEM-modified myosin beads[1]to block unmodified free thiols in samples[2]as a supplement in IP lysis/wash buffer for in vitro SUMOylation assay[3]
- Biochem/physiol Actions: Augments currents from native M-channels in sympathetic neurons and acts as an opener for KCNQ2, KCNQ4 and KCNQ5 channels.
