Validation of the URPD system by PCR analysis of the blaOXA resistance gene. Lane 1: 496 bp blaOXA amplified products for the blaOXA resistance gene. Lane 2: 451 bp blaOXA amplified products for the blaOXA resistance gene. Lane 3: 330 bp blaOXA amplified products for the penicillin-binding protein. The products were run on a 1%-agarose gel with a 100 bp ladder as a molecular size marker (Lane M)
