  • Patent number: 4857453
    Abstract: A device is disclosed for conducting an assay method. The device comprises a housing, means enclosed in the housing for capturing a member of a specific binding pair in a zone and for allowing liquid to be transported by capillary action away from the zone, one or more self-contained liquid reagents enclosed in the housing for conducting an assay method for the determination of an analyte in the sample, and means in the housing for introducing the sample into the device. Preferably, the self-contained reagents are liquid reagents which are contained in a breakable container. The device of the invention finds use in assay methods for the determination of an analyte in a sample suspected of containing the analyte. Kits for conducting an assay method are also disclosed.

  • Patent number: 4849338
    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).

  • Patent number: 4847195
    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.

  • Patent number: 4837395
    Abstract: Methods and compositions are provided for assays involving members of a specific binding pair ("sbp members") and members of a signal producing system ("sps members"). The signal producing system is capable of producing a detectible signal in relation to the presence or amount of an analyte in a sample suspected of containing the analyte. Exemplary of sps members are enzymes and enzyme substrates, which react with each other to produce a signal. The improvement of the present invention comprises temporarily delaying the production of the signal without subsequent reagent addition. The delay can be achieved by employing an inhibitor which can be an alternate substrate for the enzyme or a compound which reacts with the product of the enzyme and its substrate in an effective amount.

  • Patent number: 4837239
    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.

  • Patent number: 4833384
    Abstract: An assembly is described for accurately and precisely controlling the position of a plunger in a syringe to deliver precise fluid volumes. The assembly includes a motor coupled to a lead screw that drives a bearing block along a linear guide rod to move the plunger of the syringe in a linear fashion. The position of the plunger is accurately controlled by attaching a digital encoder to the rotating motor shaft. The encoder and associated electronics output to a controlling processor that generates a series of regular pulses, typically 300 to 500 responsive to each motor revolution. Utilizing appropriate gear ratios of the motor and the lead screw, the number of pulses per full syringe stroke in typical applications can be on the order of one hundred thousand. The final position and the motion of the plunger (velocity and acceleration) can be controlled to within a few encoder pulses, thus precisely controlling the rate of delivery of the fluid and the volume of the fluid actually delivered by the syringe.

  • Patent number: 4830786
    Abstract: Squaraine dyes and compositions of matter containing such dyes are disclosed. The squaraine dyes have an absorption maximum greater than 600 nanometers and are particulary useful in conjunction with a helium/neon (He/Ne) laser. Some of the squaraine dyes are hydrophilic and are therefore water soluble or water compatible and others of the squaraine dyes are lipophilic.

  • Patent number: 4812401
    Abstract: Compounds and methods are disclosed for reversibly aggregating particles suspended in a liquid medium. The method comprises combining the liquid medium containing the particles with a polyionic polymer capable of aggregating the particles under conditions suitable for such aggregation. Thereafter, the particles are contacted with a chemical reagent capable of cleaving the polyionic polymer under conditions sufficient to reverse the aggregation. Optionally, magnetic particles are added to the liquid medium in the present method under conditions for non-specific binding and the medium including the aggregates is subjected to a magnetic field gradient to separate the aggregates from the medium. The compounds of the present invention are polyions. The aggregation of the particles is reversible upon contact with chemical agents which cleave at least some of the bonds within the polyionic polymer.
