NUCLEIC ACID PURIFICATION METHOD, NUCLEIC ACID EXTRACTION METHOD, AND NUCLEIC ACID PURIFICATION KIT

WIPO Patent Application WO/2013/038604

A1

[Problem] To provide a nucleic acid purification method which involves simple operations and can purify nucleic acid at high efficiency in a short time. [Solution] A nucleic acid purification method including a procedure for adsorbing a substance, included in a sample containing nucleic acid, by an ion exchange resin (10), a cation exchange resin and an anion exchange resin being used for the ion exchange resin (10). A first cation exchange resin and a second cation exchange resin having a lesser molecular weight exclusion limit than that of the first cation exchange resin may be used for the cation exchange resin.
