Visual detection of EV71 by RT-LAMP with a fluorescent detection reagent. Ten-fold serial dilutions of viral RNA (lanes 1 to 6, 1 to 0.00001 PFU per reaction mixture, respectively) were detected. (A) Evaluation under normal light. The color of positive samples changed from orange to green, whereas the color of negative samples and the negative control remained orange. (B) Evaluation under UV light. Positive samples were bright green under UV light, while negative samples or the negative control remained weakly green.
