Description

Aldrithiol-4 was used as cosubstrate in a study to develop highly specific inhibitors against mannose-binding lectin-associated serine proteases byin vitroevolution technology:phage display.It was used to study the O2equilibria of recombinant human neuroglobin and cytoglobin measured under close to physiological conditions.It was used to modify gold surfaces for protein studies.
