Figure 3From: Comparison of DNA extraction kits for PCR-DGGE analysis of human intestinal microbial communities from fecal specimens Average DNA yield obtained using the four commercial kits as influenced by fecal dry matter. The percent dry matter in the human fecal specimens were 26%, 35%, and 41% (n = 45/kit). Values for DNA yield were normalized based on the dry weight of the respective fecal sample. DNA from the fecal specimens were extracted using Mobio Ultra Clean® Fecal DNA Isolation Kit (M), QIAamp® DNA Stool Mini Kit (Q), FastDNA® SPIN Kit (FSp), and FastDNA® SPIN Kit for Soil (FSo).Back to article page
