Abstract
This protocol describes a general method for the preparation of RNAs in which the reactivity or hydrogen-bonding properties of the molecule are modified in a photoreversible fashion by use of a caging strategy. A single caged adenosine, modified at the 2' position as a nitro-benzyl ether, can be incorporated into short RNAs by chemical synthesis or into long RNAs by a combination of chemical and enzymatic synthesis. The modified RNAs can be uncaged by photolysis under a variety of conditions including the use of a laser or xenon lamp, and the course of this uncaging reaction may be readily followed by HPLC or thin-layer chromatography.
