An object of the present invention is to provide: a method for isolating and purifying nucleic acids which employs a solid phase wherein the solid phase has excellent isolating capability, good washing efficiency, and easy workability, and can be mass produced with substantially identical isolating capability, the solid phase being used in a method for isolating and purifying nucleic acids by adsorbing nucleic acids in a sample onto a solid phase surface and desorbing the nucleic acids by washing and the like; and a unit for isolation and purification of nucleic acid which is suitable for carrying out said method. The present invention provides a method for isolating and purifying a nucleic acid, comprising the step of: adsorbing a nucleic acid onto a solid phase composed of an organic high polymer having a hydroxide group on a surface thereof, and desorbing the nucleic acid from the solid phase, and a unit for isolation and purification of nucleic acid comprising a container having at least two openings wherein the container contains a solid phase composed of organic high polymers having a hydroxyl group on a surface thereof.
本发明的目的是提供一种用于分离和纯化核酸的方法,该方法采用一种固相,其中固相具有优异的分离能力、良好的洗涤效率和易操作性,并且可以以基本相同的分离能力批量生产,该固相用于通过将样品中的核酸吸附到固相表面并通过洗涤等方法解吸核酸来分离和纯化核酸的方法;以及一种适用于实施所述方法的核酸分离和纯化装置。本发明提供了一种分离和纯化核酸的方法,包括以下步骤:将核酸吸附到由表面带有羟基的有机高聚物组成的固相上,并从固相中解吸核酸;以及一种用于分离和纯化核酸的装置,包括一个至少有两个开口的容器,其中容器含有由表面带有羟基的有机高聚物组成的固相。
