Abstract
Systems and methods are provided for microbial identification using cleavable tags. Control information is sent to a mass spectrometer to select a peptide labeled with a first tag of a known microbe, fragment the labeled peptide of the known microbe, and monitor for an intensity of the first tag in an MRM method using a processor. An ion source provides a beam of ions from a sample that includes peptides labeled with the first tag. The first tag binds to a peptide of a known microbe and is cleaved from the peptide of the known microbe during mass spectrometry. The mass spectrometer receives the beam of ions and is adapted to perform the MRM method on the beam of ions. If the intensity of the first tag received from the mass spectrometer exceeds a threshold value, the known microbe is identified in the sample using the processor.
