Figure 1: Representative agarose gel of multiplex PCR products from six selected multidrug-resistant isolates (lanes 1-6) showing M. tuberculosis-specific amplification of 473 bp and 235 bp fragments (marked by arrows) of oxyR and rpoB genes, respectively. Lane M is 100 bp DNA ladder and the position of migration of 100 and 600 bp fragments are marked.
