Figure 2From: Comparative analysis of four methods to extract DNA from paraffin-embedded tissues: effect on downstream molecular applicationsInternal control amplification. Mean Ct value of PhHV PCR of the 4 materials (A, B, C and D) for the different extraction methods. The +/ and -/ indicate the use of proteinase K digestion or no digestion, respectively. The different extraction methods are indicated by: heat-treatment =/-, QIAamp DNA extraction =/Q, EasyMAG DNA extraction =/EM, Gentra DNA extraction =/G.Back to article page
