Abstract: Edman Degradation is one of the N-terminal amino acid sequence analysis methods for peptide chains/proteins sequencing. The protein is reacted with PTC under weakly basic conditions and then treated with an acid to free the amino-terminal residue of the peptide chain in the form of PTH-AA for subsequent analysis. Peptide Mapping analysis is an effective method for rapidly localizing protein sequences and is a commonly used strategy in protein identification. The method uses mass spectrometry for peptide analysis and compares the obtained spectra with a protein database to obtain amino acid information. De Novo Protein Sequencing is a method based on the enzymatically cleaved peptides that exhibit regular fragmentation in mass spectrometry to obtain amino acid information from the mass differences in regular mass spectral peaks. Summary: Edman Degradation is one of the N-terminal amino acid sequence analysis methods for peptide chains/proteins sequencing. The protein is reacted with PTC under weakly basic conditions and then treated with an acid to free the amino-terminal residue of the peptide chain in the form of PTH-AA for subsequent analysis.References: https://www.creative-proteomics.com/services/proteomics-service.htm Report abuse »
