  • Patent number: 6255089
    Abstract: Mutations have been discovered in mammalian G protein-coupled serotonin 5-HT2A and 5-HT2C receptors which render the mutated receptors constitutively active. An alignment methodology based on the highly conserved sixth transmembrane domain has been discovered for the monoamine receptors which accurately predicts the amino acid position in the third intracellular loop which, when mutated, produces constitutive activation of the receptor. Constitutive activation of the G protein-coupled serotonin receptors has been shown by the demonstration of an enhanced affinity and potency for serotonin, by increased basal activity of the second messenger system in the absence of agonist, and by reduction of the basal second messenger activity by inverse agonists.

  • Patent number: 5227159
    Abstract: B-cell lymphomas express surface immunoglobulin (immunoglobulin) containing unique idiotypic (idiotype) determinants which may be exploited as tumor specific markers. The inventor has produced murine monoclonal antibodies (MAbs) reactive with the idiotype marker derived from 67 patients with low grade, follicular, small cleaved cell lymphoma. Out of 199 monoclonal antibodies, 47 (24%) were found to react with pooled normal human serum immunoglobulin in concentrations ranging from 0.6 .mu.g/ml to 160 .mu.g/ml. Of these 40 monoclonal antibodies, 90% cross-reacted with idiotype present in normal serum in levels <50 .mu.g/ml. Thirty-two of these anti-idiotypes were directed against a shared idiotope expressed on another patient's lymphoma cells. The frequency of shared idiotope expression defined by each antibody ranged from 0.26% to 3.9% of the B-cell lymphomas tested. A panel of five anti-idiotype antibodies reacted with 80% of AIDS associated lymphomas.

  • Patent number: 5196351
    Abstract: A novel bidentate conjugate has two different chemical moieties, or bidentate members, attached through an adequate spacer moiety. Each bidentate member acts as a small molecule ligand and is capable of specifically binding to a different macromolecular substance. The bidentate members are relatively small molecules, usually less than about 7,000 Daltons in size. The spacer moiety is selected so that both bidentate members can simultaneously bind to their respective specific binding partners. Where the specific binding partners are multivalent, large complexes can be formed. The formation of these complexes can be inhibited by the presence of an unconjugated monovalent bidentate member, such as free analyte from a test sample. The bidentate is of particular use in turbidimetric or nephelometric inhibition immunoassay procedures.

  • Patent number: 5168057
    Abstract: A trifunctional conjugate is provided having three chemical moieties, attached through a spacer moiety. At least two of the chemical moieties are relatively small molecules, usually less than about 7,000 Daltons in size. The spacer moiety is selected to impart certain steric properties to the conjugate. In one embodiment, the binding of a macromolecular specific binding partner to one of the chemical mouths sterically inhibits the binding of a different macromolecule to another chemical moiety. In another embodiment, the binding of a first chemical moiety to a macromolecule restricts the subsequent binding of a second chemical moiety to a proximate location on the same macromolecule.

Three sides of each panel are sealed together, preferably by an adhesive, most preferably by heat sealing, such that an opening to an internal region is created, said opening defined by the top, unsealed portion of the front panel, and the top unsealed portion of the back panel which exceeds the height of the front panel. The region of the back panel extending above that of the front panel is referred to as a "flap" or "flap region". The flap region includes means for folding the flap along a substantially parallel line to said opening, said line being located above the opening, preferably from between about one-fourth to about one-half of the distance of the flap upwards from said opening and most preferably about one-fourth of the distance of said flap upward from said opening.

  • Patent number: 5145567
    Abstract: Disclosed herein is a methodology for analyzing isoenzymes using capillary zone electrophoresis ("CZE") techniques. Briefly, an isoenzyme-containing sample and a substrate capable of being catalyzed by said isoenzyme into a reaction product are introduced into a capillary column comprising a buffer. Most preferably, the buffer contains the substrate prior to introduction of the sample into such substrate-buffer. CZE separation techniques are applied to the column such that the isoenzymes are separated from each other into discrete zones. The separation techniques are terminated such that product is rapidly generated by the catalytic conversion of substrate by the isoenzymes, and accumulated, within each discrete zone, followed by detection of product. Information regarding the relative distribution of the isoenzymes can be derived from the relative distribution of the product.
