Abstract:
The present invention involves a method for detecting the unique aberrant gene transcripts of a targeted cellular genomic abnormality in a tissue sample. This method comprises a series of steps. Initially, total cellular RNA or m-RNA is preferred from the tissue sample to be analyzed for the presence of a genomic abnormality. The total cellular RNA or m-RNA is then mixed with at least one synthetic DNA oligonucleotide complementary to the unique RNA sequence of the targeted cellular genomic abnormality being detected. The mixing is under conditions facilitating formation of double stranded DNA-RNA heteroduplexes when a strand of synthetic DNA oligonucleotide is complementary to an RNA strand obtained from the tissue sample. The conditions are those such as time, salt concentration, temperature and pH 10. The synthetic DNA oligonucleotide is preferably about several hundred nucleotides in length, more preferably about 60 to about 150 nucleotides in length.
