COOH-PEG-COOH is a homobifunctional PEG derivative, generally used to modify proteins, peptides and other substances with amino or other acid-reactive chemical groups.

COOH-PEG-COOH can increase solubility and stability and reduce the immunogenicity of peptides and proteins. It can also inhibit the non-specific binding of charged molecules to the modified surface.

Biopharma PEG offers a wide range of PEG products from lab to commercial scale in both non-GMP and GMP grades. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
