Figure 2From: Evaluation of cost-effective total nucleic acids extraction protocols for cultured Mycobacterium tuberculosis; a comparison by PCR amplification of genes associated with drug resistancerpoB , KatG and rrs gene amplifications product of DNA obtained with protocol 4. DNA extracted from five cell suspensions with protocol 4 were amplified separately by PCR for three genes. Amplification products of the rpoB, KatG and rrs genes obtained separately by PCR were each resolved at 70 Volts for 1 hour on a 2% agarose mini-gel containing 0.001 mg/mL ethidium bromide.Back to article page
