Optimization of LAMP reaction temperature (A, B) and reaction time (C, D).
Assessment was based on HNB visualization of color change in (A) and (C) and on gel electrophoresis in (B) and (D). M = 100-bp ladder. In (A) and (B), 1 = 60°C, 2 = 61°C, 3 = 62°C, 4 = 63°C, 5 = 64°C and 6 = 65°C. In (C) and (D), 1 = 15 min, 2 = 30 min, 3 = 45 min, 4 = 60 min and 5 = 90 min.
