Confirmation and detection of MTBC-MCDA products. A The LFB and MG methods were applied for IS6110 gene amplification. The products of the MTBC-MCDA assay were visually analyzed by observation of TL1 and color change. Tube 1/biosensor 1: positive amplification of M. tuberculosis; Tube 2/biosensor 2: black control of DW. B The LFB and MG methods were applied for mpb64 gene amplification. The products of the MTBC-MCDA assay were visually analyzed by observation of TL2 and color change. Tube 3/biosensor 3: positive amplification of M. tuberculosis; Tube 4/biosensor 4: black control of DW. C The LFB and MG methods were applied for both IS6110 and mpb64 gene amplification. The products of the MTBC-MCDA assay were visually analyzed by observation of TL1, TL2 and color change. Tube 5/biosensor 5: positive amplification of M. tuberculosis; Tube 6/biosensor 6: black control of DW
