Figure 3From: Rapid detection of sacbrood virus (SBV) by one-step reverse transcription loop-mediated isothermal amplification assayDetection of LAMP products by observing white turbidity and color of the reaction mixture. (A) Shows white turbidity of the reaction mixture by magnesium pyrophosphate; (B) Shows color (green) of the reaction mixture after adding SYBR Green I. 1-5, reaction carried out using 10-fold serial dilutions of standard SBV DNA (1.0 × 104 copies/μL): 1: 1.0 × 100, 2: 1.0 × 101, 3: 1.0 × 102, 4: 1.0 × 103, and 5: 1.0 × 104 copies/μL, respectively.Back to article page
