Metallothionein (MT), a cysteine-rich metalloprotein that is purported to play an important role in heavy metal accumulation and detoxification, and its related peptidic species were attached onto dithiobissuccinimidyl propionate self-assembled monolayers. The spatially accessible sulfhydryl groups present in these immobilized biomolecules, tagged with N-biotinoyl-N'-[6-maleimidohexanoyl]hydraz...

Blankenship, L. C. (Eastern Utilization Research and Development Division, Washington D.C.), and M. J. Pallansch. Differential analysis of sulfhydryl and disulfide groups of intact spores. J. Bacteriol. 92:1615-1617. 1966.-Fluorescence quenching of fluorescein mercuric acetate in alkaline medium (1 n NaOH) was found to be an accurate, sensitive method for differential analysis of sulfhydryl and...

The effect of N-ethylmaleimide (NEM), an irreversible sulfhydryl modifying reagent, on the transport of organic cations in the renal basolateral membrane was examined. The studies were conducted examining the exchange of [3H]tetraethylammonium (TEA) for unlabeled TEA in basolateral membrane vesicles isolated from the outer cortex of rabbit kidneys. NEM inactivated TEA transport in a dose-depend...
