Latest Patents

Kari Kataja's latest patents include a method for determining amounts of polynucleotide sequences present in cell or tissue samples. This invention relates to a method and test kits designed for the quantitative determination of polynucleotide amounts in a sample. The test kit features organized pools with polynucleotide probes of distinct sizes, which may be equipped with tracer tags or primer tags. The probes hybridize with affinity-tagged analyte polynucleotides from the sample, resulting in hybrids that can be recovered using a separation aiding tool. This invention allows for sensitive and quantitative assessments of polynucleotide variations in response to inherent changes or external stimuli.

Another significant patent is the development of a microfluidic chip device (MCD) for performing miniaturized assays on magnetic microbeads (MMs). This device is particularly useful for miniaturized transcript analysis through affinity capturing assays, including PCR. The MCD consists of at least one reaction chamber with sealable liquid connections and fluidic pillar filters that allow MMs to pass. The design enables effective manipulation of the liquid stream and MMs, facilitating advanced experimental procedures.
