Detection of Salmonella enterica subsp. enterica via Quenching of Unincorporated Amplification Signal Reporters in Loop-Mediated Isothermal Amplification
Table 3
In vitro specificity of the negative and positive control panels. Specificity testing included various available samples and strains containing the target sequence (positive control panel) as well as samples containing nucleic acids that were expected to present negative results in the assay (negative control panel).
