Agarose gel electrophoresis of the PCR amplification products of S. aureus, mecA gene (1.5% agarose, 70 V, 45 min.). L: the DNA molecular weight marker (100 bp ladder). Lanes 1, 2, 3, 5, and 7: positive PCR amplification of 533 bp for mecA gene. Lanes 4, 6, and 8: negative PCR amplification of 533 bp for mecA gene. N is a PCR product of negative control.
