Fig. 1

Agarose gel of multiplex allele-specific (MAS)-PCR amplicons obtained from M. tuberculosis H37Rv containing wild-type (I572) sequence (lane Rv) and rifampicin-resistant isolate 5177/06 containing I572F mutation (lane F572) at rpoB codon 572 obtained with NArpoBF, NArpoBR, and NArpoB572F primers. The position of migration of 232 bp and 78 bp fragments are indicated by arrows. Lane M is 100 bp DNA ladder and the positions of migration of 100 bp, 300 bp and 600 bp fragments are marked
