Amplification products for protocol 1, 2 and 5 respectively. a) rspL b) rrs c) KatG genes DNA extracted from five cell suspensions with each of the protocols 1, 2 and 5 were amplified by PCR for three genes. Amplification products of the rpoB, KatG and rrs genes obtained were each resolved at 70 Volts for 1 hour on a 2% agarose mini-gel containing 0.001 mg/mL ethidium bromide.
