Popis: We report the first cellular application of a photoclick SPAAC reagent to label azide-functionalized RNA. 350 nm irradiation of a cyclopropenone caged oxo-dibenzocyclooctyne (photo-ODIBO) biotin yields formation of the SPAAC reactive species, which rapidly forms adducts with RNA containing 2′-azidoadenosine (2′N3-A). Photo-ODIBO was found to be highly stable in the presence of thiols, conferring greater stability relative to ODIBO. Light activated photo-ODIBO enabled tagging of cellular RNA, in addition to fluorescent imaging as well as enrichment of RNA in cell subpopulations via selective irradiation.
