Methoxy PEG aldehyde, Mp 20000

Methoxy PEG aldehyde (mPEG-CHO) is a PEG derivative functionalized with an aldehyde (-CHO) group, allowing for Schiff base (imine) formation or reductive amination with primary amines. The methoxy-terminated PEG chain ensures high solubility, low immunogenicity, and biocompatibility, making it ideal for bioconjugation, hydrogel crosslinking, and surface modifications.

Applications:
Bioconjugation & PEGylation: Forms stable imine or secondary amine linkages with biomolecules for protein, peptide, and antibody modification.
Hydrogel & Polymer Crosslinking: Reacts with amine-functionalized polymers, enabling biocompatible hydrogel formation for tissue engineering.
Nanoparticle Functionalization: Used to stabilize drug delivery carriers, ensuring longer circulation times in biological systems.
Surface Chemistry: Modifies biosensor surfaces and implant coatings, allowing for controlled ligand attachment.
