ApplicationsReagent 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 significantly dependent on pH.
Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package
