Orduna A, Beaudry F. Scientific Poster Purpose: Describe a sensitive, robust HRAM LC-MS method to detect and identify marker proteins in raw meat samples.
Methods: Well-defined proteogenomic annotation, carefully selected surrogate tryptic peptides, and analysis using a hybrid quadrupole-Orbitrap MS were integrated.
Results: The targeted method allowed for the detection of undesired meat species down to 1% (w/w) of the entire sample. Myoglobin tryptic peptides from each species were detected with an observed m/z below 1.3 ppm.
