Introduction
This kit combines bead grinding and column purification techniques and is suitable for rapid extraction of high-purity total DNA from ≤200mg stool samples. The purification column selects high-performance ultrafine glass fiber filter membrane as the material, which efficiently and specifically adsorbs DNA. This kit adopts silica gel column purification technology and a unique salt mediated adsorption method, which can efficiently remove RNA and inhibitory factors. The entire process does not require phenol chloroform and can efficiently adsorb humic acid and other inhibitory factors in the solution. Purified DNA can be directly used for experiments such as PCR, Southern hybridization, enzyme digestion, and second-generation sequencing.
