Carboxylic PEG acid, mPEG-COOH

Description:

Carboxylic acid functionalized methoxyl polyethylene glycol, PEG acid (mPEG-COOH) is a mono reactive PEG derivative that can be used to modify proteins, peptides and other materials via amino or other acid reactive chemical groups. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

Physical Properties:

• Off-white/white solid or viscous liquid depends on molecule weight;
• Soluble in regular aqeous solution as well as most organic solvents;

Storage Conditions:

• Store at -20 ⁰C, dessiccate. Protect from light. Avoid frequent thaw and freeze.
