In this work we describe methods for the analysis of RNAs that have been edited by the double-strand RNA-specific adenosine deaminase, ADAR. These RNAs contain inosine residues that can be detected and quantified by a variety of approaches, including base hydrolysis and thin-layer chromatography, reverse transcription polymerase chain reaction, primer extension, and inosine-specific base cleavage. The most common method for the analysis of editing will be described here. This method involves complete hydrolysis of edited RNAs to nucleo-side monophosphates, followed by separation of the products using thin-layer chromatography.
