METHOD FOR SEPARATING AND PURIFYING NUCLEIC ACID, CARTRIDGE FOR SEPARATING AND PURIFYING NUCLEIC ACID AND KIT FOR SEPARATING AND PURIFYING NUCLEIC ACID

摘要

PPROBLEM TO BE SOLVED: To provide a method for separating and purifying nucleic acid, which has excellent separation performance and improved cleaning efficiency, is simple and rapid, has excellent automation and miniaturization suitability and in which a porous membrane having substantially the same separation performance and being mass produced is used. PSOLUTION: In the method for separating and purifying nucleic acid comprising (1) a process for passing a sample solution containing nucleic acid through a nucleic acid adsorbing porous membrane to adsorb nucleic acid on the porous membrane, (2) a process for cleaning the porous membrane on which nucleic acid is adsorbed and (3) a process for desorbing nucleic acid from the porous membrane by using a recovering liquid, the nucleic acid adsorbing porous membrane is a porous membrane on which nucleic acid is adsorbed by interaction substantially not associated with an ionic bond and a process for drying the porous membrane having adsorbed nucleic acid is not included between the cleaning process and the recovery process.
