WebPCR can also be used to test for a bacterium or DNA virus in a patient's body: if the pathogen is present, it may be possible to amplify regions of its DNA from a blood or tissue sample. Sample problem: PCR in forensics Suppose that you are working in a forensics lab. - [Voiceover] I'm here with Emily, our biology content fellow, to talk about … WebPCR-ESI/MS. PCR-ESI/MS uses the mass-to-charge (m/z) ratio of a PCR amplicon to infer its base composition. The method uses primers targeted to conserved regions in the bacterial genome, as well as species-specific regions for accurate identification, and produces PCR products of different length and composition (Figure 1).
