To identify contaminants and genetically modified matter, in agricultural foodstuffs, a solution of the proteins is electrophoresed and analyzed by mass spectrometry to give individual peptide mass fingerprints

摘要

Identifying natural or genetically modified biological contaminants in foodstuffs by extraction, comprising forming a solution of the proteins contained in the sample, separating the proteins by bi-dimensional electrophoresis, and following digestion by a proteolytic enzyme, obtaining the molecular mass of the obtained peptides by mass spectrometry to give a peptide mass fingerprint, is new.
