Biological Activity for TBIA

TBIA (trans-bis-isatoic anhydride) is a bifunctional SHAPE (selective 2'-hydroxyl acylation analyzed by primer extension) chemical cross-linking reagent. TBIA has two electrophilic isatoic anhydride moieties, both of which can react with the 2'-OH group in nucleotides adjacent to and distant from the primary RNA sequence. TBIA is used in SHAPE-JuMP (-juxtaposed merged pairs) a technique for exploring RNA tertiary structure proximity on large RNAs, and higher-order RNA-RNA interactions at nanometer resolution.
