• • Disulfide Bond Mapping in Recombinant Protein Drugs

  Recombinant protein drugs are a class of drugs with proteins as the main active ingredients. Their molecular weight is usually much larger than traditional small molecule drugs, and their structure is more complex. Recombinant protein drugs can directly act on molecular mechanisms in the body, possessing high specificity, strong biological activity, and relatively low side effects.

• • Mass Spectrometry Reveals Links Between Exosomal Proteins and Cell Development

  Proteomics is a research field that uses mass spectrometry to identify and quantify proteins on a large scale in biological tissues and cells. Through proteomic techniques, comprehensive information about tissues, cells, and even individual proteins can be obtained, broadening our understanding of biological processes.

• • Mass Spectrometry Revealing Molecular Mechanisms in Proteomics

  Mass spectrometry analysis is a powerful tool that can accurately and effectively analyze the mass, chemical structure, and relative abundance of substances.
