ABSTRACT:
The present invention discloses improved compositions and methods for detecting mutations, including single base changes, in nucleic acid sequences using RNase protection assays. The improvements include concomitant, dramatic reductions in the salt and RNase enzyme concentrations in the RNase digestion reaction mixture which result in greater sensitivity in detecting genetic mutations. Another embodiment of the present invention is kits to be used for the detection of single base mismatches in nucleic acid samples.
