MS2 uses its filamentous structure, pili, to transfer its genetic material into the bacterial cell. The sensitivity of the MS2 assay makes it a great tool to screen for product efficacy before conducting more intensive research. It is possible to operate a TQMS in four different modes5 (Figure 3), namely:- Precursor ion scan the first quadrupole (Q1) is scanned over a mass range to select the precursor of a specific product ion (m/z value) which is then monitored in the last quadrupole (Q3).-Product ion scan Q1 is set to transmit only the pre-defined precursor (m/z) to the collision cell, while Q3 is scanned over a mass range to identify the fragments obtained under the experimental condition.-Neutral loss (NL) both Q1 and Q3 are scanned to identify all the precursors that give rise to the products by the loss of the same neutral (uncharged) species from all the precursors. Diagnostic systems based on reverse transcription (RT)-PCR are widely used for the detection of viral genomes in different human specimens.
