TIANamp Stool DNA Kit is based on silica membrane technology for stool sample gDNA extraction. The spin column is made of new type silica membrane which can bind DNA optimally on given salt and pH conditions. Simple centrifugation processing completely removes impurity, proteins and other organic compound. The gDNA isolated with these products is of high quality, high purity and full-length. Purified gDNA is ready for use in downstream applications such as PCR. - Wide range of application: Suitable for solid or liquid feces samples from different sources. - Simple and fast: Ultrapure genomic DNA can be obtained within 1 hour. - High purity: High efficiency precipitant can remove impurities such as humic acid, the purity of extracted DNA is very high, which can be directly used in downstream experiments.
