Peptide mapping

Peptide mapping is a widely used approach for analyzing biopharmaceuticals, including antibody, protein and peptide. In order to obtain the full sequence information of the targeted protein, APTBIO uses up to 3 kinds of proteases for protein digestion (Trypsin, Chymotrypsin and Glu-C). After protein digestion, sequences of peptide are mapped for full-length sequence of biopharmaceuticals. APTBIO has developed LC-MS/MS based peptide mapping technology, ensuring accurate peptide mapping analysis. This technology can be used to analyze the sequence of biopharmaceuticals and confirm complete expression of recombinant protein.
