Figure 2From: Use of Multiple Displacement Amplification as Pre-polymerase Chain Reaction (Pre-PCR) to amplify genomic DNA of siphonapterids preserved for long periods in scientific collectionsAmplification, without the use of the MDA technique, of the 200 bp fragment of the 16S mtDNA of samples from scientific collections preserved in 70% ethanol and stored at room temperature. 1) 100 bp DNA Marker; 2) Tunga penetrans (control); 3) Ctenocephalides felis felis (control); 4) C. felis felis (2008); 5) T. penetrans (2007); 6 and 7) T. caecata (2005 and 2007); 8) Negative control.Back to article page
