General description

N-Ethyl-d5-maleimide is a deuterated isotope analog of N-ethymaleimide, wherein methylene and methyl protons are replaced by deuterium.

Application

N-Ethyl-d5-maleimide can be used:
  • To synthesize isotopic silica nanotag by reacting with silica precursor 3-mercaptopropyltrimethoxysilane (MPTMS) for multiplexed ion beam imaging.
  • As an isotopic internal standard to determine the ratio of glutathione (GSH) and glutathione disulfide (GSSG) in cultured cells using HPLC-UV and LC-QTOF-MS.

Packaging

This product may be available from bulk stock and can be packaged on demand. For information on pricing, availability and packaging, please contact Stable Isotopes Customer Service.

Several diseases are associated with perturbations in redox signaling and aberrant hydrogen sulfide metabolism, and numerous analytical methods exist for the measurement of the sulfur-containing species affected. However, uncertainty remains about their concentrations and speciation in cells/biofluids, perhaps in part
