Amino-PEG13-amine(CAT: I016276) is a linear, bifunctional polyethylene glycol (PEG) linker terminated with primary amine groups at both ends of a 13-unit PEG chain. The dual amines provide versatile reactive handles for coupling with carboxylic acids, activated esters, or other electrophiles, enabling the formation of stable amide or carbamate linkages. The PEG13 spacer offers extended length, high flexibility, and excellent hydrophilicity, improving solubility and reducing steric hindrance in conjugation reactions. This reagent is widely applied in bioconjugation, surface modification, polymer chemistry, and drug delivery research, where long, flexible PEG spacers are required to enhance biomolecule stability and reduce aggregation.
