Method for determining amounts of polynucleotide sequences present in cell or tissue samples
The invention is related to a method and test kits for quantitative determination of polynucleotide amounts present in a sample. The test kit comprises organized pools with polynucleotide probes having distinct sizes and optionally provided with tracer tags or primer tags. The probes are allowed to hybridize with affinity tagged analyte polynucleotides from the sample. The result is hybrids, which can be recovered on a separation aiding tool provided with the pair of the affinity tag. After the quantitative release of the probes, the probes are either directly recorded, or if primer tagged, they are amplified and optionally provided with a tracer tag before recording. The invention provides a sensitive and quantitative determination of the amount polynucleotides present in a cell or tissue sample and allows a quantitative assessment of variations in the amounts of polynucleotides as a response to inherent changes or due to external stimuli.
