Figure 6From: Comparison of DNA extraction kits for PCR-DGGE analysis of human intestinal microbial communities from fecal specimens Dendrograms generated from PCR-DGGE profiles obtained from DNA extracted using the four commercial kits. The dendrograms were based on Unweighted Pair Group Method with Arithmetic Averages (UPGMA). Dendrogram A is based on 35 to 50% DGGE gradient gel and dendrogram B is based on 45 to 60% DGGE gradient gel.Back to article page
