Light Yellow Powder

A highly reactive thiol-specific spin-label. A specific conformational probe of thiol site structure by virtue of its minimal rotational freedom and distance from the covalent disulfide linkage to the macromolecule under study.

ChEBI: (1-oxyl-2,2,5,5-tetramethylpyrroline-3-methyl)methanethiosulfonate is an aminooxyl that is pyrroline substituted by an oxidanediyl group at position 1, by methyl groups at positions 2, 2, 5 and 5, and by a [(methylsulfonyl)sulfanyl]methyl group at position 3. It is a highly reactive thiol-specific spin label. It has a role as a spin label. It is a member of aminoxyls, a thiosulfonate ester and a pyrroline.

MTSSL is a cysteine-specificflexible disulfide bond forming paramagnetic nitroxide spin label probe. MTSSL is reported to be useful for investigating structural and conformational dynamics of membrane proteins and protein aggregation.
