Amine Reactive

Payload Delivery Linkers and Modifiers | Uniform mPEG Modifiers: Amine Reactive

Amine-reactive uniform mPEG (methoxy polyethylene glycol) modifiers are PEG derivatives with a terminal reactive group—commonly NHS ester or isocyanate—that selectively forms covalent bonds with primary amines on biomolecules. These reagents are used to modify proteins, peptides, or surfaces to improve solubility, reduce immunogenicity, and prolong circulation time in vivo. The uniform mPEG structure ensures consistent molecular weight and predictable performance in drug delivery, diagnostics, and therapeutic formulation.
