1-mercapto-11-hydroxy-3,6,9-trioxaundecane

Description

Thiol-PEG4-Alcohol is a crosslinker containing a hydroxyl group and a thiol group. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydrophilic PEG spacer increases solubility in aqueous media.

Uses

• Oligo-ehtylene glycol of peptides and small molecules (PEGylation)
• PEG-disulfide formation
• ultra-thin protein-resistant monolayers
• Densely packed monolayer and a flexible-hydrophilic oligo ethylene glycol arm for avoiding non-specific adsorption
