Peptide Synthesis Service

Peptides have emerged as potent catalysts for advancing the diagnosis and therapeutics of rare diseases due to their distinct biological activities. Our company specializes in delivering high-quality peptide synthesis services and possesses a range of peptide synthesis platforms that can aid in your research endeavors aimed at developing peptide therapies for rare diseases.

Introduction to Peptide Synthesis

Peptide synthesis is the process of linking amino acids in the order of C-terminus (carboxylic end) to N-terminus (amino end). Since the successful development of the solid-phase peptide synthesis method by Merrifield in 1963, peptide synthesis has been continuously improved and refined and has become a common technique in the development of rare disease drugs. It serves as the foundation for the development of rare disease polypeptide therapy.

Synthetic polypeptides have shown promise in rare disease therapy. They can be used as probes for diagnosis and imaging, coupled with nanomaterials for targeted therapy, or developed as peptide vaccines to activate the immune system for prevention. Synthetic peptides have demonstrated good stability and can target specific molecules or signaling pathways in tumor cells.
