Peptide Mapping And Amino Acid Analysis. Due to the heterogeneous nature of protein drugs extensive analytical characterization is required. Overview of peptide and protein analysis by.

The peptide fragments should be identified to the extent possible. Peptide mapping showed that the major antigenic regions of the CP are in descending order of strength the C-terminal 20 amino acids aa 5 aa in the central region of the protein and 5 aa at the N-terminus. Subsequently the derivatized terminal amino acid is removed by acid cleavage in a form of phenylthiohydantoin PTH derivative and a new α-amino group on the next amino acid is now available for the next round of reaction with PITC.
Peptide structure analysis to evaluate fragmentation strategies for peptide mapping and to detect atypical amino acids that might be present in a protein or peptide.
Subsequently the derivatized terminal amino acid is removed by acid cleavage in a form of phenylthiohydantoin PTH derivative and a new α-amino group on the next amino acid is now available for the next round of reaction with PITC. High-performance liquid chromatographic peptide mapping and amino acid analysis in the sub-nanomole range. It is necessary to hydrolyze a proteinpeptide to its individual amino acid constituents before amino acid analysis. Protein analysis and peptide mass mapping of a model sample of horse heart myoglobin by LCMS using a quadrupole mass spectrometer is introduced below.
