A pretreatment kit includes a container ( 10 ) for particle manipulation, nucleic acid capture particles ( 70 ) capable of selectively binding to nucleic acid, aqueous-phase separation medium ( 21, 22, 23 ), a plurality of kinds of aqueous liquids ( 35, 31, 32, 38 ), and a nucleic acid for individual identification. The nucleic acid for individual identification is contained in at least one of the plurality of kinds of aqueous liquids or is bound onto the surfaces of the nucleic acid capture particles. The base sequence of the nucleic acid for individual identification contains an identification sequence including a base sequence noncomplementary to the nucleic acids contained in the biological sample. The pretreatment kit is used for separating nucleic acids from biological samples that contains nucleic acids and contaminants. |
