Fig. 6From: Multiple Cross Displacement Amplification Coupled with Lateral Flow Biosensor (MCDA-LFB) for rapid detection of Legionella pneumophilaOptimized reaction time for MCDA assay. Four different reaction times (A, 25 min; B, 35 min; C, 45 min; D, 55 min) were tested and compared at optimal amplification temperature (65 °C). Biosensors 1, 2, 3 and 4 represent DNA template levels of 10 fg/μL (LoD level). The best sensitivity was seen when the amplification lasted for 35 minBack to article page
