PEG polymers have many inherent good biological properties, including high water solubility and lack of toxicity, immunogenicity and antigenicity. Therefore, in many applications, the chemical modification of bioactive compounds, such as peptides, antibody fragments, enzymes or small molecules with polyethylene glycol chain, so called PEGylation, usually leads to improved pharmacokinetics and biological function.
Abvigen provide high quality PEG products with low polydispersity, high reactivity and high purity, and bioconjugation services by site specific ligation of PEG to peptides, proteins, oligonucleotides, antibodies, lectins, enzymes, toxins, drugs or other small molecules.
