Advances in Protein and Polypeptide Drug Analytics

With the rapid advancement of biotechnology, protein and peptide drugs have become increasingly widespread in the medical field, yet their metabolic processes are complex and require the assistance of modern analytical methods for research. Based on the latest domestic and international research, this paper systematically reviews the application of modern analytical methods in the metabolism of protein and peptide drugs. The research focuses on key technologies such as biological activity detection, mass spectrometry, and chromatography, elaborating on their principles, characteristics, and current state of development. The aim is to provide scientific evidence and technical support for drug development, and to promote in-depth research on the metabolism of protein and peptide drugs.
