Description

Amino-PEG2-(CH2)3COOH features a short, hydrophilic PEG spacer flanked by an amine and a terminal carboxylic acid group. This bifunctional architecture enables site-specific conjugation in bioconjugation workflows, offering enhanced solubility and stability under physiological conditions.

Application

Amino-PEG2-(CH2)3COOH serves as a versatile bifunctional linker for bioconjugation and peptide synthesis, combining the solubility and stability of a short PEG chain with orthogonal reactive handles. The primary amine enables coupling to carboxylate-functionalized surfaces or biomolecules, while the terminal carboxylic acid facilitates further conjugation via amide bond formation. Its well-defined structure ensures consistent performance in solid-phase synthesis and protein labeling workflows.
