METHOD OF ISOLATING NUCLEIC ACID USING MATERIAL POSITIVELY CHARGED AT FIRST PH AND CONTAINING AMINO GROUP AND CARBOXYL GROUP

摘要

A method of isolating nucleic acid from a sample containing nucleic acid is provided. The method includes contacting the sample with a bifunctional material that contains an amino group and a carboxyl group and is positively charged at a first pH to allow binding of the nucleic acid to the bifunctional material; and extracting the nucleic acid at a second pH higher than the first pH from the complex.
