  • Serum hepatitis test
    Patent number: 4034072
    Abstract: Reagent and method for detecting the presence of hepatitis associated antigen (HAA) in blood serum. The reagent comprises anti-HAA antibodies coupled via an intermediate silane to a plurality of siliceous particles having a surface area of at least about 1 m.sup.2 /g and, if the particles are porous, an average pore diameter of at least about 1000 A. The test method comprises the steps of incubating a serum sample with the reagent to complex any HAA in the samplewith the antibodies of the reagent, incubating the reaction product with a solution of radio labelled anti-HAA antibodies to complex the labelled antibodies with any HAA that may be complexed to the reagent, separating the incubation products from the solution of labelled antibodies, and counting the radioactivity of either the separated products or the remaining solution to determine whether HAA was in the sample.

  • Reagent and method for TBG assay
    Patent number: 4032626
    Abstract: The concentration of thyroxine binding globulin (TBG) in a fluid sample can be determined via radioassay technique with an immunochemical composite comprising anti-TBG antibodies immobilized on a water-insoluble carrier. The composite is incubated with the sample in a quantity sufficient to assure complexation of substantially all TBG in the sample to the antibodies of the composite. The quantity of TBG complexed is determined with radiolabeled thyroxine (T.sub.4) which complexes with at least a portion of the complexed TBG. By separating the labeled composite from the remaining labeled T.sub.4, and counting the bound (or unbound) T.sub.4, the concentration of TBG can be determined from a standard curve.

  • Electrically heated outlet system
    Patent number: 4029887
    Abstract: An apparatus for heating glass-forming materials within a delivery conduit extending from an electric glass melting furnace to a connector channel is disclosed. The conduit is made from an electrically conductive refractory metal such as molybdenum and is used to conduct current from inside the furnace to its exit end in the channel. Joule effect heating between the exit end of the conduit and an electrode in the connector channel indirectly causes the glass materials within the conduit to partially melt, to the extent that the materials within the conduit may be exhausted from the conduit. A flange assembly for use with a molybdenum conduit is also disclosed.

  • Enzyme carriers
    Patent number: 4025667
    Abstract: The half-life of enzymes which have been immobilized by chemical coupling via silane coupling agents to inorganic carriers is increased significantly by using a carrier which has been treated to increase its water-durability. Treatment of the carrier comprises the steps of first coating the carrier with a solution containing a metal, the oxide of which is more water-durable than the carrier, and then firing the coated carrier to form a continuous metal oxide layer on the carrier surface. The treated carriers are then silanized for chemical coupling wih enzymes. Methods for preparing and using enzyme composites having the improved carrier are disclosed.
