Chemicals
PCR reaction mixture to a total volume of 20 mL consist of ±2 ng template(Chromosome of Klebsiela pneumoniae ITB1); each 0.2 µM of forward and reverse primers: and KAPA Taq Mix 1x Extra Hotstart containing dNTP(dATP, dTTP, dCTP) 0.1 mM: 1x PCR buffer(2 mM MgCl2, 1 mM tris-Cl buffer pH 8, gelatin 0.001%); and Taq DNA polymerase of 0.25 units. PCR was performed a number of 34 cycles at a denaturation at 95 °C for 2 minutes, annealing for 0.5 minutes at the appropriate temperature(Tm-5) °C of the primers, and elongation for 2.0 minutes at temperature of 72 °C. At the final stage of the cooling process is carried out for 5 minutes. PCR results showed by a band of DNA under UV light in electrophoresis gel
