Application

  • Aldrithiol™-4 was used as cosubstrate in a study to develop highly specific inhibitors against mannose-binding lectin-associated serine proteases by in vitro evolution technology:phage display.
  • It was used to study the O2 equilibria of recombinant human neuroglobin and cytoglobin measured under close to physiological conditions.
  • It was used to modify gold surfaces for protein studies.

The effect of oxidants on Ca(2+) movement in osteoblasts is unclear. In this study, we show that 4,4'-dithiodipyridine (4,4'-DTDP), a reactive disulphide that mobilizes Ca(2+) in muscle, induces an increase in cytoplasmic free-Ca(2+) concentrations ([Ca(2+)](i)) in MG63 human osteosarcoma cells

The active site cysteine of human O(6)-alkylguanine-DNA alkyltransferase (hAGT), Cys145, was shown to be highly reactive with model electrophiles unrelated to substrates, including 1-chloro-2,4-dinitrobenzene. The high reactivity suggested that the Cys145 thiolate anion might be stable at neutral pH. The

Members of the Sco protein family are implicated in the assembly of the respiratory complex cytochrome c oxidase. Several possible roles have been proposed for Sco: a copper delivery agent, a site-specific thiol reductase, and an indicator of cellular redox

Dipyridyl disulfide (DPS) is a highly reactive thiol oxidant that functions as electron acceptor in thiol-disulfide exchange reactions. DPS is very toxic to yeasts, impairing growth at low micromolar concentrations. The genes TRX2 (thioredoxin), SOD1 (superoxide dismutase), GSH1 (gamma-glutamyl-cysteine synthetase)
