An object of the present invention is to provide a method capable of removing contaminants other than nucleic acids derived from feces at high efficiency, and thereby obtaining nucleic acids with high purity, although it is difficult to purify nucleic acids in high purity from feces. n In the present invention, a feces sample is purified using a quaternary ammonium salt such as, for example, hexadecyltrimethylammonium bromide. |
