Gel documentation of multiplex PCR using primer set 3 for detecting two ESBL genes of E. coli (blaSHV and blaOXA-1) isolated from Sonali chicken meat (image cropped for clarity). Lane 1 = 1500 bp DNA marker; lane 2 = negative control; lane 3 = blaSHV (795 bp); lane 4 = blaSHV (795 bp) & blaOXA-1 (564 bp); lane 5 = blaOXA-1 (564 bp); lane 6 = blaSHV (795 bp) & blaOXA-1 (564 bp); lane 7 = blaSHV (795 bp); lane 8 = negative sample. The original gel image is presented in supplementary figure S7.
