Silane-PEG-COOH (MW 5000)

Silane-PEG-COOH (MW 5000) is utilized for modifying proteins, peptides, and other materials with active groups. The carboxyl group (-COOH) readily forms stable amide bonds with amino groups and ester bonds with hydroxyl groups. Silane-functionalized PEG (Silane-PEG-X) is suitable for surface modification of glass, silicon, and similar substrates.
