Quick Answer
Learn professional peptide PEG modification and PEGylation technology for biomedical and life science research. Serve global manufacturer, factory, wholesale supplier, biotech company and laboratory.
Peptide drugs have shown great potential in the field of disease diagnosis and treatment due to their high activity, low toxicity and high specificity. However, peptide drugs also have some limitations, such as peptides are easily degraded by enzymes in vivo, resulting in a short duration of efficacy and the need for frequent administration, and some peptides may trigger an immune response, affecting the therapeutic efficacy and side effects, and the peptides are poorly water-soluble, which affects his bioavailability. To overcome these challenges, we have successfully developed polyethylene glycol (PEG) modification to significantly improve the pharmacokinetic properties and increase the stability of peptide drugs. pharmacokinetic properties of peptide drugs, improving their stability and bioavailability.
Technological Breakthroughs
- Controlled modification: A variety of PEG derivatives and linker arms have been developed to precisely control the length, branching structure and linkage of PEG molecules to optimize the modification effect.
- Multi-functional modification: Combining PEG modification with other modification technologies (e.g. fatty acid modification, glycosylation modification, etc.) to provide peptide drugs with more functionalities, such as targeting and slow release.
- Site-specific modification: Through chemical synthesis, PEG molecules are precisely attached to the specific sites of peptides to avoid affecting their active sites.
Technical Advantages
Prolonged half-life: PEG modification can increase the size of peptide molecules, reduce renal filtration, and protect peptides from enzymatic degradation, thus significantly prolonging their half-life.
