BioChain's stool DNA extraction kit is a convenient and easy to use means of extracting high purity genomic DNA from stool samples. This kit does not require organic extraction with toxic reagents such as phenol or chloroform, or loss-inducing precipitation steps. The lysis-binding and wash buffers are formulated to remove contaminants that may inhibit downstream applications, such as next generation sequencing, PCR, and methylation studies that are key to a better understanding of gastrointestinal cancers such as colorectal cancer.
