In this study, samples identification through detection of lacZ
and uidA genes using PCR simultaneously (multiplex PCR) was
approved. Primers listed in Table 1 are used to amplify 876 bp
and 147 bp fragments of lacZ and uidA genes, respectively.
Amplification reaction in a final volume of 25 mL contains 5 mL
of diluted bacteria or purified DNA; and 2.5 micro liters buffer
containing 10 Xmg, 1 mL dNTPs, 1.5 units of Taq enzyme and
2 mL of both primers were added to it. The PCR reaction steps
were as follows.
