Screening of optimal primer pairs using RPA amplification reactions. Agarose gel images show the amplification results of five primer pairs designed for bla KPC (A), bla NDM (B), bla OXA-48-like (C) and bla IMP (D) genes. The name of each primer pair is above each lane: Lane M is DNA ladder. NTC lanes are template-free controls for the respective primer pairs. Band sizes of the DNA ladders are shown on the left.
