Peptide Drug Quality Peptide Map Analysis

Polypeptide drugs are bioactive substances composed of two or more amino acids with significant therapeutic effects. They have broad applications in many fields, including the treatment of diabetes, cardiovascular diseases, tumors, etc. The advantages of polypeptide drugs lie in their high specificity and low side effects, but their stability and bioavailability are relatively low. Therefore, the development of polypeptide drugs needs to ensure their structural integrity and high activity to enhance their efficacy.

Quality peptide mapping is an important method for quality control of polypeptide drugs. By using mass spectrometry, it provides a detailed analysis of the structure of polypeptide drugs, including the sequence of amino acids, chemical modifications, and disulfide bond positioning. Mass spectrometry displays the mass-to-charge ratio and intensity of each ion, thereby determining the relative position and quantity of each amino acid residue. This not only helps us understand the structure and properties of the drug but also allows for the timely detection of issues in the drug preparation process, such as incomplete synthesis, oxidation, dehydration, etc.

Schematic of Quality Peptide Mapping for Bioproduct Characterization

Bright Peak Biotech (BTP) manages laboratories with an ISO9001 certified quality control system and is recognized by the national CNAS laboratory, providing drug quality research services that comply with global regulatory standards. Based on high-resolution chromatography and mass spectrometry platforms,Polypeptide Drug Quality Peptide Mappingtechnology can effectively separate each peptide in complex samples, and mass spectrometry can fragment peptides to generate a series of peptide ions, thus obtaining sequence information of the peptides. This is crucial for the identification, quantification, and functional research of peptides, and can be used to confirm the integrity, structure, and modification of peptides, providing key information for the development and clinical application of polypeptide drugs. We also offer customized technical services to meet the diverse needs of clients. Free consultations available.
