Method of isolating and purifying a nucleic acid

摘要

A method of isolating and purifying a nucleic acid, comprises the steps of: (1a) passing a sample solution containing a nucleic acid through a nucleic acid-adsorptive porous membrane to adsorb the nucleic acid to the nucleic acid-adsorptive porous membrane under a specific condition; (2a) passing a wash solution through the nucleic acid-adsorptive porous membrane to wash the nucleic acid-adsorptive porous membrane while adsorbing the nucleic acid under a specific condition; and (3a) passing a elution solution through the nucleic acid-adsorptive porous membrane to desorb the nucleic acid from the nucleic acid-adsorptive porous membrane under a specific condition.
