Abstract

An inorganic porous carrier including a linker of formula (1) and having mode diameter of 0.04 μm to 1 μm in a pore distribution and the density of voids having an opening area of 0.0025 μm2 or more of 12 to 30 voids/μm2 [a bond * represents a linkage to the oxygen atom in a silanol group of an inorganic porous substance; n is an integer; R represents an alkyl group containing 3 to 10 carbon atoms which may optionally have a substituent such as an alkoxy group; and L represents a single bond; an alkylene group of 1 to 20 carbon atoms; or an alkylene group containing 2 to 20 carbon atoms containing —CH2-Q-CH2— group wherein Q selected from a group consisting of —O— etc. is inserted into at least one of —CH2—CH2— group constituting the alkylene group]; and a method for preparing a nucleic acid using the same.
