Abstract: A method for determining the presence of a polynucleotide analyte in a sample suspected of containing the analyte is disclosed. The method comprises combining in an assay medium the sample and first and second polynucleotide reagents complementary to the analyte. Each of the first and second reagents hybridize with a different region of the analyte. The first reagent contains means for rendering the first reagent non-covalently polymerizable. The second reagent contains means for rendering the second reagent detectable. The sample and the first and second reagents are combined in the assay medium under conditions for polymerizing the first reagent wherein the second reagent becomes bound to the polymerized first reagent only when the analyte is present in the sample. A determination is then made as to whether the second reagent has become bound to the polymerized first reagent.

Abstract: Combinations of 9-(1,3-dihydroxy-2-propoxymethyl) guanine or a pharmaceutically acceptable salt thereof, with .beta.-interferon show a surprisingly high degree of synergism in their activity against viral infections.

Abstract: An assay method and compositions are provided for determining the presence of an analyte in a sample. The analyte is a member of an immunological pair (mip) comprising ligand and receptor. By providing a first measurement surface capable of specifically binding a labelled reagent in an amount depending upon the presence of analyte in the sample and a second calibration surface capable of binding a second labeled reagent in a manner unaffected by the presence of analyte in the sample, calibration of individual tests can be accomplished simultaneously with the performance of the test itself. A signal producing system includes an enzyme, a catalyst usually bonded to a mip which defines the first labeled reagent for binding to the measurement surface and the same catalyst conjugated to a ligand capable of binding to the calibration surface. Preferably, both labeled reagents have the same composition and the calibration surface include anti-(first catalyst).

Abstract: Polyiodothyronine analog conjugates to glucose-6-phosphate dehydrogenase (G6PDH) are provided which find use in the determination of polyiodothyronine compounds, particularly thyroxine, normally in physiological fluids, such as serum. The G6PDH enzyme activity can be substantially reduced when bound to antibodies specific to polyiodothyronine as compared to the free or unbound polyiodothyronine analog enzyme conjugates. The polyiodothyronine analog is conjugated to the G6PDH by a linking group having a chain one atom in length.

Abstract: This invention is directed to a formulation of cardiotonic phosphodiesterase inhibitors with a water-soluble vitamin, comprising a lyophilization step performed on a solution of the complex in an aqueous/organic solvent system. The formulation results in a complex that has been found to have enhanced solubility (over the compound alone) in a parenterally or orally acceptable solvent, and the lyophilization process yields a product with superior stability permitting an extended shelf life.
