It is a single-stranded RNA molecule that functions as a regulatory molecule. This method is less time-intensive and costly than using mammalian host cells. Bacteriophage MS2 ( Emesvirus zinderi ), commonly called MS2, is an icosahedral, positive-sense single-stranded RNA virus that infects the bacterium Escherichia coli and other members of the Enterobacteriaceae. While the optimal injection volume is dependent on the experimental conditions, it is possible to inject as little as 0.1 L up to as much as 100 L of the sample accurately using an autosampler.1 The mobile phase is continuously pumped through a column (a stainless-steel tube) usually filled with silica particles coated with another liquid, the stationary phase. By operating the MS in SIM or SRM mode, it is possible to achieve limits of detection in the range of ng/mL or even pg/mL. The propagation of viral strains and the maintenance of host cells is notoriously time consuming, which can make virus disinfection studies take a long time to complete.
