Eosinglutathione as a fluorescent glutathione derivativee
Eosinglutathione has a high fluoresence whereas dieosinglutathione disulfide (DiEGSSG) is strongly quenched. This property combined with a negligable activity of DiEGSSG as a substrate for glutathione reductase is the basis for use in glutaredoxin assays.
The glutaredoxin assay kit FkGRX-01 kit determines glutaredoxin activity with oustanding sensitiviy.
DiEGSSG is also a product.
