Figure 3From: Usefulness of real time PCR for the differentiation and quantification of 652 and JP2 Actinobacillus actinomycetemcomitans genotypes in dental plaque and saliva Real time PCR melting curve and agarose gel electrophoresis results obtained using a suspension containing a mixture of two genotypes: a single curve is obtained with two distinct Tms' peaks which confirm good system selectivity. Melting peak at 73°C in negative control and the small band in the control samples "C" are primer dimer products.Back to article page
