Maleimide PEG carboxylic acid, Mp 5000

Maleimide PEG Carboxylic Acid is a functionalized PEG containing a maleimide (-C=CH-NH-C(O)-) group for thiol reactivity and a carboxyl (-COOH) group for further conjugation via amide bond formation. It is commonly used for dual conjugation applications in biomaterials, drug delivery, and biointerface engineering.

Applications:
Hydrogel Crosslinking: Enables thiol-maleimide chemistry for covalent hydrogel network formation.
Bioconjugation & Protein Labeling: Facilitates dual-site modifications for targeted drug delivery.
Nanoparticle Stabilization: Improves colloidal stability and functionalization of nanoparticles.
Medical Device Coatings: Enhances biocompatibility and hydrophilicity of biomaterials.
