<p>A process for detection of one of a number of closely realted genes including the steps of: (i) carrying out a PCR assay including one or more DNA test samples from a human, animal or plant DNA cell extract in combination with at least one reference standard which includes a DNA cell extract having a first gene normally found in such DNA cell extract in a copy number of 1 or more per cell and a second gene closely related to the first gene but usually present in the DNA cell extract in a copy number of 0, 1, 2 or more together with a first primer specific for said first gene, a second primer specific for said second gene and a third primer common to both the first gene and the second gene; and (ii) determining the presence of the second gene in said DNA test sample(s) by comparison of the test sample(s) with said at least one reference standard.</p> |
