What is peptide sequencing?
Peptide sequencing is an essential step in the analysis of peptides and complex biomolecules. It enables the exact order of amino acids within a peptide chain to be determined, providing key information for pharmaceutical research, biotechnology and the food industry.
Peptide sequencing stages
From the precise determination of the sequence to the study of specific modifications, each phase offers information to better understand and exploit peptides in your processes.
- Sequence determination: identify the precise amino acid sequence of a peptide using advanced techniques such as Mass Spectrometry (MS/MS).
- Analysis and encoding: obtaining and encoding the sequence for functional studies or peptide production.
- Cleavage and modification: studying signal sequences or specific regions to identify critical modifications or active sites.
