Title:
PRODUCTION METHOD FOR SINGLE-STRAND RNA
Document Type and Number:
WIPO Patent Application WO/2021/024467
Kind Code:
A1
Abstract:
The present invention provides a production method that is for single-strand RNA and that comprises: (I) a step for causing an RNA ligase which has double-strand nick-repairing activity and is classified as EC6.5.1.3, which is an enzyme number defined by the International Union of Biochemistry, to act on first single-strand RNA having a phosphate group at the 5' end and second single-strand RNA having a hydroxy group at the 3' end so that the first single-strand RNA and the second single-strand RNA are linked together; and (II) a step for purifying a reaction product containing the single-strand RNA generated in the linking step (I) by reversed-phase column chromatography using a mobile phase containing at least one salt selected from the group consisting of monoalkylamine salts and dialkylammonium salts.
