Fig. 2From: Prevalence of bla TEM-220 gene in Penicillinase-producing Neisseria gonorrhoeae strains carrying Toronto/Rio plasmid in Argentina, 2002 – 2011Discrimination of PPNG isolates with the G547A substitution in bla TEM allele by using T220-f/T220-r primers. Lanes 1 and 2, indicate the 204 bp PCR products from strains IM4519 and IM4520 with the G547A mutation in bla TEM allele; lanes 3, 4, 5 and 6 indicate PPNG control strains containing bla TEM-1 and bla TEM-135, respectively, without amplification; lane M, molecular size markerBack to article page
