Usage

General Description

3-[2-(2-maleimidoethoxy)ethylcarbamoyl]-proxyl is a chemical compound that is commonly used in biochemical and medical research as a spin label for various biological molecules. It is a stable nitroxide radical that can be used in electron paramagnetic resonance (EPR) spectroscopy to study the structure and dynamics of proteins, nucleic acids, and membranes. The maleimidoethoxy group in its structure allows for specific labeling of cysteine residues in proteins, making it a valuable tool for studying protein-protein interactions and conformational changes. Additionally, its stability and relatively long half-life in biological systems make it an ideal tool for long-term studies of physiological processes.
