FIGURE 4

Agarose gel electrophoresis of round 1 and round 2 PCR reactions. (A) No PCR products corresponding to the correct sized product were seen following 10 cycles of long range amplification. Lanes from left to right correspond to the following samples: 1 Kb + marker (Invitrogen), High molecular weight marker (Invitrogen), SCCmec I–XI, no template negative control. (B) Round 2 orfX and mecA reactions show the correct sized amplicon in the orfX reaction, while most types produce weak and multiple bands in the mecA reaction. Lanes from left to right in each gel correspond to the following samples: 1 Kb + marker (Invitrogen), SCCmec I-XI, no template negative control.
