Abstract
The bioluminescent assay in real time (BART) is a molecular diagnostic tool for the detection of nucleic acid amplification by recording light output. The key component for BART is a thermostable luciferase derived from the firefly Photinus pyralis. Coupling BART detection with the isothermal amplification method loop-mediated isothermal amplification (LAMP) enables rapid molecular diagnostic results using simple equipment. LAMP-BART provides quantitative results from a closed tube and is appropriate to microliter standard tests and nanoliter microfluidic assays. In this chapter, we introduce a protocol to amplify and detect genetic markers using LAMP with BART. Furthermore, we provide advice to optimize LAMP assays for high sensitivity and specificity and to eliminate the incidence of "false positive" results which can occur from the components of the assay. The optimization of genetically modified (GM) maize by targeting the nopaline synthase terminator (NOSt) and 35S promoter (35Sp) sequences is described.
