  • Patent number: 5843634
    Abstract: This invention relates to genetically engineered enzymes, their ligand conjugates, their manufacture, and their use in qualitative or quantitative assays. A hybrid enzyme, such as an AP-epitope, has a foreign amino acid moiety (an epitope) inserted near the active site of the starting AP enzyme. The foreign amino acid moiety binds with an analyte, and, as a consequence of this binding, the enzymatic activity of the hybrid enzyme, AP-epitope, is modified. The changes in the enzymatic activity are dependent upon the presence, or the amount, of the analyte. In another embodiment, the hybrid enzyme consists of a cysteine introduced near the active site of an AP to give a hybrid enzyme. The cysteine on the hybrid enzyme serves as a point of conjugation of a ligand, such as theophylline, ferritin, thyroxine, or digoxigenin, to form the hybrid enzyme-ligand conjugate.

  • Patent number: 5840501
    Abstract: A method for determining the complexed forms of immunologically determinable prostate specific antigen (cPSA) in a blood sample, e.g., by two-site immunometric assays, in which the blood sample is treated to render free PSA (fPSA)immunologically nondetectable. A particularly preferred immunometric assay method employs three anti-PSA antibodies: an antibody that binds to both cPSA and fPSA (anti-tPSA), a second anti-tPSA antibody which is characterized by the unique property that binding to fPSA is blocked by binding of fPSA-specific antibodies, and a third antibody which is a fPSA-specific antibody. Thus, binding of the fPSA-specific antibody to PSA in the sample allows only cPSA to be measured in the immunometric assay. Measurement of cPSA blood levels has been found to provide a method for aiding in the diagnosis and monitoring of prostate cancer that is highly sensitive and specific, and eliminates the need for a significant number of patients to undergo unnecessary prostate biopsy.

  • Patent number: 5739002
    Abstract: This is a method for reproducing in vitro the serine protease activity associated with the HCV NS3 protein, that comprises using both of the sequences contained in NS3 and the sequences contained in NS4A. This method takes advantage of the ability of the HCV NS4A protein, or sequences contained therein, to act as a cofactor of the serine protease activity or more generally of the enzymatic activities associated with NS3. Optimal serine protease activity is obtained when NS4A is present in a molar ratio of at least 1:1 with NS3. NS3 and NS4A can also be incorporated in the reaction mixture as NS3-NS4A precursor, as this precursor will generate, by means of an autoproteolytic event, equimolar amounts of NS3 and NS4A. It is also possible to mutate the cleavage site between NS3 and NS4A in a procursor, so that NS4A remains covalently The sequences that do not influence the proteolytic activity of NS3 can subsequently be removed from protease activity.

  • Patent number: 5631137
    Abstract: Disclosed and claimed are methods for selecting a recombinant virus, phage or cell expressing a catalytic antibody or catalytic portion thereof, or for selecting catalytic activity by a moiety. The method employs reaction-based selection for catalytic activity. The method can also be used to concentrate (increase the proportion of catalytic to non-catalytic moieties) a sample containing a catalytic moiety or viruses, phages or cells expressing a catalytic moiety. The selection or concentrating can be by employing a mechanism-based inhibitor, catalysis-accelerated movement, surface binding, changes in enthalpic component of binding as a function of temperature, or changes in binding by competition, or combinations thereof. The invention also comprehends a method for producing a recombinant virus or a cell-line expressing a catalytic moiety such as a catalytic antibody or catalytic portion thereof; and, this method can include infecting a suitable host with viruses which are screened for the expression.

  • Patent number: 5610019
    Abstract: Isolated polynucleotide molecules encoding mammalian phospholipid transfer proteins (PLTP) and phospholipid transfer protein polypeptides are disclosed. The DNA molecules are transformed or transfected into host cells and the cells cultured to produce recombinant PLTP and PLTP polypeptides. PLTP and PLTP polypeptides may be combined with a pharmaceutically acceptable vehicle and administered to patients to regulate phospholipid transfer activity and thereby obtain a more favorable lipoprotein profile in the blood. The proteins and polypeptides may also be used within methods to measure phospholipid transfer activity or identify inhibitors of phospholipid transfer activity.

  • Patent number: 5605809
    Abstract: The present invention provides for novel reagents whose fluorescence increases in the presence of particular proteases. The reagents comprise a characteristically folded peptide backbone each end of which is conjugated to a fluorophore. When the folded peptide is cleaved, as by digestion with a protease, the fluorophores provide a high intensity fluorescent signal at a visible wavelength. Because of their high fluorescence signal in the visible wavelengths, these protease indicators are particularly well suited for detection of protease activity in biological samples, in particular in frozen tissue sections. Thus this invention also provides for methods of detecting protease activity in situ in frozen sections.

  • Patent number: 5571681
    Abstract: Molecules having covalent catalytic activity are identified by panning synthetic and semisynthetic combinatorial libraries on solid phase suicide substrates. In an alternative mode, mechanism-based inhibitors or affinity labels may substituted for the suicide substrate. Covalent catalysts within the combinatorial library form covalent conjugates with the suicide substrate, mechanism-based inhibitor, or affinity label. Covalent conjugates are immobilized by attachment to the suicide substrate to solid phase and are easily separated from unconjugated elements of the combinatorial library by stringent washing. Combinatorial libraries employing phagemid-display are particularly preferred since such phagemids include genetic material for identifying and amplifying conjugated catalysts. Covalent catalysts obtainable by this method include, inter alia, molecules having esterolytic activity, aldol condensation activity, .beta.-lactamase activity, glycosidase activity, RNase activity, and proteolytic activity.
