Figure 4From: Comparative analysis of four methods to extract DNA from paraffin-embedded tissues: effect on downstream molecular applicationsAssessment of maximum amplicon length: visualisation on gel. Gel image of 200-400-600 bp multiplex PCR-products of representative tissue B. 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. Neg = ultrapure water in PCR, Pos = QIAamp extracted DNA from EDTA-blood.Back to article page
