Chemische Eigenschaften
white to orange crystalline powder
Verwenden
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.
Definition
ChEBI: An organic disulfide obtained by formal oxidative dimerisation of 4-thiopyridine.
l?uterung methode
Recrystallise the disulfide from H2O, EtOH, Me2CO, *C6H6 or pet ether. It has been used as a 1mM solution in EtOH for the spectrophotometric estimation of thiols. Essentially the thiol displaces half the disulfide molecule liberating the 4-mercaptopyridine (4-pyridinethiol) anion, thereby shifting the max from 324nm (of the disulfide) to 285nm (of the anion) at pH 9. (Compare with 2,2’dipyridyl disulfide above which has been used for the same purpose.) [Humphrey et al.
