mPEG-SG

Synonyms: Methoxy-PEG-SG; Methoxy polyethylene glycol-SG; Methoxy-PEG-Succinimidyl Glutarate; Methoxy polyethylene glycol-Succinimidyl Glutarate; mPEG-Succinimidyl Glutarate; mPEG-Succinimidyl Glutarate ester

mPEG-SG (Succinimidyl Glutarate) is usually a white solid. The hydroxyl end of the mPEG of this product is activated to the SG group, which can be bonded to the free amino group of the active drug, thereby effectively linking mPEG to the required materials or small molecule drugs and polypeptides to reduce non-specific binding and immunity on the surface of charged molecules Originality. MPEG-SG can react with primary amine groups in pH7-8.5 buffer. This feature allows mPEG-SG to react with amino groups on lysine in proteins or other biological molecules. mPEG-SG is widely used in the fields of medical research, drug-sustained release, biomedical polymers, and peptide synthesis carriers. This product needs to be filled with nitrogen when stored. This product is easy to absorb moisture, and its activity will decrease until it completely loses its activity after absorbing moisture. Therefore, it must be kept dry during storage, and repeated freezing should be avoided as much as possible.
