Application

TS-Link Bimane thiosulfate sodium salt is used to fluorescence label sulfhydryls found in proteins and other biomolecules such as glutathione. In contrast to the thioether bonds formed by maleimides and iodoacetamides, the disulfide bonds formed by TS-Link reagents are reversible — the TS-Link hapten or fluorophore can easily be removed using a reducing agent such as DTT or TCEP. TS-Link reagents are selective for thiols at neutral pH, whereas maleimides will react with other functional groups. TS-Link Bimane thiosulfate sodium salt may be used in comparison with other sulfhydryl coupling strategies.
