Carboxylic Acid PEGs

Polymers, Specialty Chemicals & Adjuncts

Carboxylic acid PEGs are polyethylene glycol derivatives with a terminal –COOH group, enabling amide, ester, or carbodiimide coupling to biomolecules, surfaces, or polymers. Polysciences carries a variety of linear, heterobifunctional, and multi-arm PEG-COOH products for bioconjugation, hydrogel synthesis, and surface chemistry.
