The Uses of 6,6'-DITHIODINICOTINIC ACID
6,6′-Dithiodinicotinic acid may be employed as:
- specific thiol blocker to investigate the radioprotective effect of mercaptoethylamine on the thiol level of the outer cell membrane of the Ehrlich ascites tumor cells
- modifier to investigate the polar microenvironment around the reactive Cys283 of rabbit muscle creatine kinase
- dipyridyl-dithio substrate to evaluate the protein disulfide-thiol interchange activity of the auxin stimulated NADH: protein disulfide reductase (NADH oxidase) of soybean plasma membranes
- water-soluble reagent in a study for introducing, in buffered saline, a reactive sulfhydryl group on water-soluble molecules bearing an alkyl-amino group
- chromogen for sulfhydryl groups in the Ellman method for cholinesterase determinations
- spectrophotometric determination of thiols and of total glutathione in human blood
