COOH-PEG24-NH2.HCL is a type of heterobifunctional PEG with carboxylic acid at one end and amine hydrochloride at the other end. COOH-PEG24-NH2.HCL can generate stable chemical bonds (such as amide bond, urethane bond, urea bond and secondary amine bond) to connect other molecules through the reactivity of the amino group. COOH-PEG24-NH2.HCL utilizes the esterification reaction of the carboxyl group and the hydroxyl group to form an ester bond, and the affinity substitution reaction with the amino group forms the carboxyl characteristics such as amide, thereby effectively linking PEG to the required materials or small molecule drugs and Peptide up, in order to achieve the purpose of reaction.
COOH-PEG24-NH2.HCL is generally used in targeted drug research and is widely used in the cross-linking of protein carriers and ligands.
