Description：

Mpeg-cooh is one of the carboxylic acid (- COOH) - functionalized polyethylene glycol derivatives, which can be used to modify proteins, peptides, particles and other materials with free acid groups. Carboxylic group is easy to react with amino group to form stable amide bond. They can also react with hydroxyl groups to form unstable ester bonds, which can be cleaved under acidic or alkaline conditions. PEGylation can increase solubility and stability, and reduce the immunogenicity of peptides and proteins. It can also inhibit the nonspecific binding of charged molecules to the modified surface. Acid functionalized peg has been widely used in the fields of medical device modification, biomolecule PEGylation and particle surface functionalization.

Handling and use：

Attention should be paid to temperature difference and air humidity to prevent moisture absorption. In the reaction as far as possible in the inert gas protection.

Ptorage condition：

Store at - 20 ℃ and keep away from light. Avoid frequent thawing and freezing.
