    摘要: The invention relates to a method and test kit for quantitative determination of the amounts or relative proportions of polynucleotides in a mixture. The invention enables assessment of dynamic variations in a mixed population of organisms using affinity aided solution hybridization. The test kit comprises organized pools of polynucleotide probes having approximately the same number of nucleotides, which are distinguishable using resolution enabling tags providing the probes with different sizes. The resolution enabling tags may simultaneously act as tracer, affinity or primer tags. The probes are allowed to hybridize with affinity tagged analyte polynucleotides. The result is hybrids, recoverable on separation aiding tools provided with counterparts of the affinity tag. After the quantitative release of the probes, the individual probes can be amplified and recorded. The method and test kit are useful for determining hygienic and epidemiologic situations and evaluating the effect of antibiotic treatment and sanitary measures.

    摘要: This invention relates to recombinant-DNA-technology. Specifically this invention relates to new recombinant yeast cells transformed with SEB1 gene. Yeast cells transformed with several copies of SEB1 gene, or overexpressing the Seb1 protein by some other means, have an increased capacity to produce secreted foreign or endogenous proteins. Further, said new recombinant cells, when transformed with genes expressing suitable hydrolytic enzymes can utilize appropriate macromolecular compounds more efficiently, which results in increased cell mass production and/or more versatile utilization of the compounds in relevant biotechnical applications.

    摘要: 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.
