AffiPEG® mPEG-AA, 350

AffiPEG® mPEG-AA, 350 is a mono-functional polyethylene glycol (PEG) derivative designed for bioconjugation and modification of biomolecules. The product is characterized by a molecular weight of 350 Daltons and features a single methoxy group on one end of the PEG chain and an amino acid (AA) on the other end. This unique structure facilitates its use in various biotechnological and pharmaceutical applications.

Applications of AffiPEG® mPEG-AA, 350

Protein and Peptide Modification:

Conjugation: AffiPEG® mPEG-AA, 350 can be used to conjugate PEG chains to proteins or peptides, enhancing their solubility, stability, and bioavailability. The amino acid functional group reacts with specific amino acid residues on the target molecule, forming stable covalent bonds.

Stability Enhancement: The PEGylation process protects proteins and peptides from enzymatic degradation and immunogenic responses, thereby extending their circulatory half-life.

Drug Delivery Systems:

Controlled Release: The PEG moiety in AffiPEG® mPEG-AA, 350 can be utilized to create prodrugs with controlled release properties. By attaching to active pharmaceutical ingredients (APIs), it can improve the pharmacokinetics and biodistribution profiles of drugs.

Targeted Delivery: PEGylation can enhance the targeting capability of drugs to specific tissues or cells, reducing off-target effects and improving therapeutic efficacy.

Biomolecule Immobilization:

Surface Modification: AffiPEG® mPEG-AA, 350 is often used to modify the surfaces of nanoparticles, microparticles, and other delivery systems. The PEG chains create a hydrophilic barrier that minimizes protein adsorption and prevents aggregation.
