The innuPREP Stool DNA Kit is suitable both for extracting bacterial DNA from stool samples as well as for isolating genomic DNA from shedded intestinal epithelial cells. The extraction process is based on sample lysis followed by a pre-filtration step to remove undissolved sample particles. The sample DNA is then bound to the surface of a spin filter membrane and washed, and the bound DNA is subsequently eluted from the spin filter column.
