Fecal DNA isolation kits allow users to effectively and conveniently extract genomic starting material from stool or fecal samples. These kits contain complete sets of reagents for purifying high yields of DNA from cells found in stool, such as host colonic cells, bacteria, viruses, and parasites. The obtained fecal DNA can then be used for downstream applications, such as PCR, microarrays, sequencing and microbiome analysis.
