Description and Uses
- 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.
