  • Patent number: 5595887
    Abstract: Methods are presented for producing and purifying a variable fusion polypeptide which can be purified by affinity chromatography with the binding protein partner. The variable fusion polypeptide construct has tandem coupled segments containing one or more copies of a desired peptide linked to carbonic anhydrase as the purification binding protein. In the methods, the fusion protein is expressed in a recombinant host using a recombinant vector containing a gene encoding the fusion polypeptide. Then the expressed fusion polypeptide is purified by immobilized reversible inhibitor affinity chromatography. Finally, the purified fusion polypeptide is cleaved from the desired peptides by chemical or enzymatic means and the desired peptides purified with affinity chromatography.

  • Patent number: 5380649
    Abstract: A process and a reagent for the determination of ions in fluids, wherein the influence of these ions on the activity of an enzyme is measured. The ions for example are sodium, potassium, calcium, magnesium, manganese, lithium, lead, zinc, copper, iron or other heavy metals or non-metallic ions comprising chloride, bicarbonate, protons, ammonium and substances that give rise to ammonium. The enzymes which are used may be a transferase, a hydrolase, an oxidoreductase or a lyase. An essential feature is a method to exclude interferences by ions by masking the interfering ions with a binding agent.

  • Patent number: 5374617
    Abstract: It has been discovered that it is possible to administer truncated tissue factor (not having the transmembrane region) (tTF) in combination with factor VIIa (F VIIa) to treat bleeding disorders such as those resulting from hemophilia or cirrhosis of the liver. The tTF is administered to produce up to 10 .mu.g tTF/ml of plasma. The F VIIa is administered to produce levels of between 40 ng VIIa/ml and 4 .mu.g F VIIa/ml of plasma. The effective dosages of both tTF and VIIa are significantly and surprisingly less than the administration of either alone to stop bleeding. Examples demonstrate safety and efficacy in normal and hemophilic dogs.

  • Patent number: 5324661
    Abstract: A method for identifying soil microbial strains which may be bacterial degraders of pollutants comprising the steps of placing a concentration of a pollutant in a substantially closed container, placing the container in a sample of soil for a period of time ranging from one minute to several hours, retrieving the container, collecting the contents of the container, and microscopically determining the identity of the bacteria present. Different concentrations of the pollutant can be used to determine which bacteria respond to each concentration. The method can be used for characterizing a polluted site or for looking for naturally occurring biological degraders of the pollutant. Then bacteria identified as degraders of the pollutant and as chemotactically attracted to the pollutant are used to inoculate contaminated soil.

  • Patent number: 5292644
    Abstract: A rapid process for detecting pathogenic microorganisms in products for human consumption comprises contacting the microorganisms with a methylumbelliferone substrate. The substrate is hydrolyzed into methylumbelliferone by an enzyme given off by the microorganisms. Hydrolysis is accelerated by sodium lauryl sulfate, which renders the microorganisms more permeable to the substrate, the enzyme, or both. The methylumbelliferone is detected by its fluorescence, either in solution or on an agar medium supporting microcolonies formed from individual microorganisms.

  • Patent number: 4252587
    Abstract: A machine for assembling a polystyrene spool by friction welding polystyrene end flanges (in the form of discs) to the polystyrene cylindrical sleeve or barrel of a spool, used for holding wire or cable wound thereon. The machine comprises a pair of coaxially spaced rotary mandrels, driven by respective motors, on which the end flange discs are first manually mounted, and a pair of cradle members for supporting a cylindrical sleeve in coaxial relation between the two mandrels. A control system is provided for initiating rotation of the mandrels with the end flanges, then causing inward movement of the mandrels toward the opposite ends of the sleeve with a predetermined air pressure to cause softening of a stepped shoulder on the end of the central polystyrene hub of the end flanges.

  • Patent number: 4159921
    Abstract: A connection apparatus mainly comprises a gas-tight container one surface of which is made of a film, a gas supply source for filling the container with a gas at a predetermined pressure, and a heat source. Two substrates, at least one of which is flexible, are tightly supported on the film surface of the container in such a manner that electrodes or terminals formed on the both substrates confront with each other. The gas pressure in the container is increased to the predetermined value, thereby to tightly contact the electrodes formed on the both substrates with each other. Thereafter, the heat source is enabled to melt the electrodes and to electrically connect the two substrates with each other.
