Figure 5. Melt curve analysis of the HIV-1 and β-actin biplex reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay.

Figure 5

Melt analysis showed products specific to HIV-1 at 78°C and β-actin at 89°C as seen in the singleplex assays. Specificity was confirmed in the presence of normal human plasma (NHP) without HIV-1 or β-actin (negative control) and showed no amplification (n = 3).
