Amino-PEG8-amine(CAT: I014114) is a homobifunctional polyethylene glycol (PEG) linker with primary amine groups at both ends of an eight-unit PEG spacer. The terminal amines readily react with carboxylic acids, activated esters (e.g., NHS esters), and other electrophilic groups to form stable amide or carbamate bonds. The PEG8 backbone enhances aqueous solubility, provides flexibility, and minimizes steric hindrance, ensuring efficient bioconjugation. With its symmetrical design, Amino-PEG8-amine is widely used in protein modification, polymer functionalization, crosslinking, and nanomaterials research. Its extended PEG spacer makes it suitable for applications requiring increased molecular spacing, hydrophilicity, and biocompatibility in drug delivery and biomaterials engineering.
