• • Analysis of Protein Vaccine Quality Peptide Map

  Recombinant protein vaccines are created through biological engineering techniques, which involves inserting a part of the coding information (DNA or RNA) of a certain pathogen (such as a virus or bacteria) into a host cell. The host cell then produces a protein from the pathogen, which is then extracted and purified to make a vaccine. Mass peptide map analysis is a mass spectrometry analysis performed on these recombinant proteins to verify their quality and structure.
