A sensitive and selective method for the paraoxon detection based on enzyme inhibition and fluorescence quenching was presented in this study. Under the catalytic effect of acetylcholinesterase (AChE), acetylthiocholine (ATCh) hydrolysis released thiocholine (TCh) which could react with N-(7-dimethylamino-4-methylcoumarin-3-yl) maleimide

The effects of lipid peroxidation on the SH reactivity of the proteins in porcine intestinal brush-border membranes were examined using a fluorogenic thiol reagent, N-[7-dimethyl-amino-4-methylcoumarinyl]maleimide (DACM) in relation to lipid organization. Changes in the lipid organization were assessed by measurement

Purified C9 with expected hemolytic and polymerizing activities was found to contain approximately 0.2 mol of sulfhydryl groups/mol of C9. By proteolysis of C9 with labeled SH groups, the SH residues on intact C9 were mapped to Cys-359 and Cys-384
