ABSTRACT:
Methods are provided for detecting and quantitating gene sequences, such as mutated genes and oncogenes, in biological fluids. The fluid sample (e.g., plasma, serum, urine, etc.) is obtained, deproteinized and the DNA present in the sample is extracted. The DNA is then amplified using an amplification procedure, such as PCR or LCR, to amplify the mutated gene sequence. In one embodiment, the DNA is contacted with a peptide nucleic acid prior to or during the amplification procedure.
