CARRIER, METHOD AND REAGENT FOR OBTAINING SMALL RNA

摘要

Disclosed are: (1) a carrier for obtaining small RNA, which is produced by introducing a polymerizable functional group or a chain-transfer group onto the surface of a core particle, mixing the particle with a polymerizable monomer, allowing the polymerization reaction to proceed to form a layer containing a polymer compound on the surface of the particle, and further immobilizing a physiologically active substance having affinity for a small RNA-binding protein on the surface of the particle; (2) a method for obtaining small RNA, which is characterized by using the carrier; (3) a reagent for obtaining small RNA and/or a nucleic acid that is targeted by small RNA, which comprises the carrier; (4) a reagent kit for obtaining small RNA and/or a nucleic acid that is targeted by small RNA, which comprises the reagent; and (5) a method for obtaining a nucleic acid that is targeted by small RNA, which is characterized by using the carrier.
