Thiol PEG Acid

Thiol PEG Acid is a polyethylene glycol (PEG)-based linker that contains both a thiol group and a carboxylic acid group, providing versatile functionality for conjugating to metal surfaces, proteins, or peptides.

The thiol group enables covalent attachment to thiol-reactive surfaces or biomolecules, while the carboxyl group allows for further functionalization or coupling to amines or other reactive groups. This dual-functional linker is commonly used in applications such as drug delivery, bio-conjugation, and surface modification of nanoparticles or other metal-based materials, improving the solubility, stability, and biocompatibility of conjugates.

Thiol PEG Acid is particularly useful in creating stable, well-defined conjugates.
