Agarose gel electrophoresis showing diagnosis of MTC by 2 PCR reactions to detect (A) the 245 bp fragment from IS6110 and (B) the 123 bp fragment from IS6110. For (A) - Lanes 1, 2, and 3 show M. tuberculosis positive specimens; Lane 4 shows a M. tuberculosis positive control with a 100bp molecular weight marker (Lane M). For B - Lanes 1,2 and 3 show the 123 bp M. tuberculosis fragment, and lane 4 shows MTB positive control
