Aurintricarboxylic acid (ATA) is a well-known inhibitor of RNA and DNA modifying enzymes and was suggested as a potent RNase inhibitor for preparation of RNA (Hallick et al., 1977, Nucleic Acids Res. 4, 3055-3064). We show that ATA is a very useful stain for detecting RNA on Northern blots and slot blots although it did not fully protect purified RNA in concentrated solution against RNase A.
