使用在第一个pH下带正电并含有氨基和羧基的物质分离核酸的方法

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.
摘要（中）：

提供了从含有核酸的样品中分离核酸的方法。 该方法包括使样品与含有氨基和羧基的双官能材料接触并在第一pH下带正电荷以允许核酸与双功能材料的结合; 以及从所述络合物中提取比所述第一pH高的第二pH的所述核酸。
