Inorganic porous support and method for producing nucleic acid using same

An inorganic porous carrier that comprises a linker represented by general formula (2), wherein a Survival Bone Rate (SBR) value is 5.0% or more.

• [wherein
• a bond marked with * represents a linkage of an inorganic porous substance to the oxygen atom of a silanol group;
• n is an integer of 1, 2 or 3;
• R represents independently of each other an alkyl group containing 3 to 10 carbon atoms which may optionally have a substituent selected from an alkoxy group and a fluorine atom;
• a phenyl group which may optionally have a substituent selected from an alkyl group, an alkoxy group, and a fluorine atom;
• a hydroxyl group;
• or an alkoxy group containing 1 to 4 carbon atom;
• L represents a single bond;
• an alkylene group containing 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 the group consisting of —O—, —NH—, —NH—CO—, and —NH—CO—NH— is inserted into at least one —CH2—CH2— group constituting the alkylene group;
• providing that a carbon atom of the methylene group bound to the group Q doses not bind to another group Q at the same time;
• Rb represents a nucleotide or a nucleotide in which a reactive group is protected or deprotected;
• and
• L1 represents a divalent group bound to an oxygen atom of a primary or a secondary hydroxy group as Rb.].
