Will qBiomarker Copy Number Assays work with heterogeneous samples like mixtures of tumor and normal tissue?

The assays will work with heterogeneous samples. However, because the tumor samples are “diluted” by the normal cells with diploid genome, the absolute observed copy number for each locus will be an average of the tumor cells and normal cells. However, the p-value should give an indication as to whether there is a statistically significant amplification or deletion that happens in the cell population for the locus of interest.
