The optimal duration of time required for MCDA-LFB assay. Four different reaction times (A, 10 min; B, 15 min; C, 20 min; D, 25 min) were examined and compared at 65°C. Strips 1, 2, 3, 4, 5, 6, 7, and 8 represent DNA levels of 10 ng of Shigella templates, 10 pg of Shigella templates, 10 fg of Shigella templates, 1 fg of Shigella templates, 0.1 fg Shigella templates per tube, negative control (L. monocytogenes, 10 pg per reaction), negative control (Salmonella, 10 pg per reaction) and blank control (DW). The best sensitivity was seen when the amplification lasted for 20 min (C).
