Cu-catalyzed azide-alkyne cycloaddition for cyclic RNA preparation
Engineering MethodCu-catalyzed azide-alkyne cycloaddition (CuAAC) is a click-chemistry method used to cyclize RNA through covalent intramolecular ligation. In a 2024 study on cyclic photocleavable RNA for a photoactivatable CRISPR/Cas9 system, CuAAC was tested alongside thiol-maleimide Michael reaction and was reported to have advantages for cyclic RNA preparation.
