Correlation between amplification times in RT-STEM-LAMP (pink) and RT-LAMP (blue) and the copy number of IVT RNA in semi-logarithmic coordinates (all dilutions were measured and detected in triplicate unless indicated otherwise). Final primers concentrations were: sHIV-BIP, sHIV-FIP, HIV-StemB, HIV-StemF, HIV-BIP, HIV-FIP, HIV-LoopB and HIV-LoopF—1.6 μM each, HIV-DisplB and HIV-DisplF—0.4 μM each. Each set of data included three NTCs that remained clean throughout the duration of the assay and were not associated with any time-to-peak value (hence not shown graphically). Error bars represent standard deviations of triplicate measurements.
