This article describes procedures to synthesize 2′-OMe-RNA modified with cross-linkable 2-amino-7-deaza-7-propynyl-6-vinylpurine (ADpVP) and preparation of the RNA-crosslinking experiment in vitro. All synthesis steps yield the desired compound in moderate or high yield without expensive chemical reagents or specific devices. The crosslink-active form of modified RNA can also be purified by commonly used reversed-phase HPLC, can be stored at −80°C after lyophilization for a few days, and is ready to use for crosslinking experiments. This crosslink-active RNA can efficiently form covalent bonds with complementary RNA in a sequence-specific manner.
