Abstract

An inorganic porous carrier including a linker of formula (1), wherein a mode diameter in a pore distribution is 0.04 μm to 1 μm, and a predetermined cumulative pore volume ratio is 30% or less [a bond * represents a linkage to the oxygen atom of a silanol group in an inorganic porous substance; n is an integer; R represents independently of each other 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 which contains —CH₂-Q-CH₂— group wherein any group 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.
