Agarose gel electrophoresis following 30 cycles of PCR performed with primers 27F and 338R and with immunocaptured fractions of B. vulgatus BrdU-labeled and unlabeled DNAs, showing robust amplification of the unlabeled control (lane 9). Lanes from left: 1, 100-bp ladder (size standard); 2, PCR positive control; 3, PCR negative control; 4, no-DNA bead supernatant; 5, no-DNA immunocaptured fraction; 6, BrdU-labeled bead supernatant; 7, BrdU-labeled immunocaptured DNA; 8, unlabeled bead supernatant; 9, unlabeled immunocaptured DNA.
