Amine Reactive

Amine-reactive uniform branched PEG modifiers are polyethylene glycol (PEG) molecules with a branched architecture and terminal reactive groups (such as NHS esters) designed to form stable covalent bonds with primary amines on proteins, peptides, or other biomolecules. This modification enhances solubility, reduces immunogenicity, and improves pharmacokinetics while maintaining structural stability.

These reagents are widely used in drug delivery, bioconjugation, and therapeutic development for controlled and site-specific functionalization.
