MTSSL

MTSSL is a paramagnetic nitroxide spin label featuring a methanethiosulfonate group for site-directed spin labeling, particularly through disulfide linkages with cysteine residues on proteins. When combined with electron paramagnetic resonance spectroscopy, site-directed spin labeling is used to study the structural dynamics of proteins, including membrane proteins.Formal Name: 2,5-dihydro-2,2,5,5-tetramethyl-3-[[(methylsulfonyl)thio]methyl]-1H-pyrrol-1-yloxy.
