Patent number: 6689566Abstract: The present invention relates to novel methods and devices for detecting whole or non-fragmented parathyroid hormone (wPTH) in a biological sample. In particular, a novel monoclonal or polyclonal antibody or antibody fragment is used that is specific for a portion of the initial peptide sequence for wPTH which comprises a domain for adenylate cyclase activation, (amino acids 2 to 8), wherein at least four amino acids in this sequence are part of the reactive portion with the antibody. The present wPTH assay can differentiate between the complete 1 to 84 amino acid sequence form of PTH and a large but incomplete 7 to 84 amino acid sequence form of PTH that is measured by commercially available “intact” or I-PTH assays. Measurement of both the complete biologically active form of PTH and the large but biologically inactive form of PTH can lead to the misdiagnosis of the parathyroid function in patients.Type: GrantFiled: January 14, 1999Date of Patent: February 10, 2004Assignee: Scantibodies Laboratory, Inc.Inventors: Thomas L.

Patent number: 6660486Abstract: Analyses of serum samples for the presence and amount of either of the two subunits of human Factor XIII protein are used as a means of eliminating a significant source of error that arises in the testing of serum and plasma.

A positive result for the presence of subunit b is a means of verifying that the sample is either serum or plasma and not any other biological fluid. A quantitative analysis of subunit b is a means of verifying that the sample is of the intended volume rather than having been reduced in volume due to improper sampling. A quantitative analysis of subunit b is also a means of verifying the dilution of a sample of either serum or plasma.Type: GrantFiled: May 31, 2001Date of Patent: December 9, 2003Assignee: Bio-Rad Laboratories, Inc.Inventors: Steven R.

Patent number: 6461823Abstract: The present invention relates to novel Death Domain Containing Receptor-4 (DR4) proteins which are members of the tumor necrosis factor (TNF) receptor family. In particular, isolated nucleic acid molecules are provided encoding the human DR4 proteins. DR4 polypeptides are also provided as are vectors, host cells and recombinant methods for producing the same. The invention further relates to screening methods for identifying agonists and antagonists of DR4 activity.Type: GrantFiled: November 24, 1999Date of Patent: October 8, 2002Assignee: Human Genome Sciences, Inc.Inventors: Jian Ni, Craig A. Rosen, James G. Pan, Reiner L. Gentz, Vishva M. Dixit

Patent number: 6451599Abstract: The invention provides monoclonal antibodies which are reactive with fibrin(ogen) degradation products (FDPS) generated by matrix metalloproteinases (MMPs), such as MMP-3, MMP-7, and membrane-type 1, MT1-MMP proteolysis of fibrinogen and cross-linked fibrin (and not plasmin or other proteases). Monoclonal antibodies of the invention include, but are not limited to, H5, F2, 90/2, 90/5, B4, 13, C6, A6, G6, E6, 197-1 and 197-2. This invention also provides methods of using monoclonal antibodies for detection of FDPs generated by proteolysis of fibrin(ogen) by MMPs, such as MMP-3, MMP-7, and MT1-MMP. In addition, the present invention provides methods for diagnosing rheumatoid arthritis, osteoarthritis, and synovitides, as well as angiogenesis, atherosclerosis, renal diseases, malignancy and inflammation.Type: GrantFiled: April 13, 2000Date of Patent: September 17, 2002Assignee: New York Blood CenterInventors: Alessandra Bini, Bohdan J.

Patent number: 6451982Abstract: A monoclonal antibody is provided which specifically binds to human interleukin-5. Also provided are a hybridoma which produces the monoclonal antibody; complementary DNAs which encode the heavy and light chain variable regions of the monoclonal antibody and CDRs therefrom; humanized monoclonal antibodies; and pharmaceutical compositions comprising the monoclonal antibody or anti-idiotypic antibodies directed against it, humanized monoclonal antibodies, binding fragments, binding compositions or single-chain binding proteins derived from the antibody and a physiologically acceptable carrier.Type: GrantFiled: March 28, 2000Date of Patent: September 17, 2002Assignee: Schering CorporationInventors: Chuan-Chu Chou, Nicholas J. Murgolo, John S. Abrams, Chung-Her Jenh, Mary E. Petro, Jon E. Silver, Stephen Tindall, William T. Windsor, Paul J. Zavodny

Patent number: 6451545Abstract: Provided are a monoclonal antibody making it possible to detect a native fibrin monomer, which is produced at the initial state of blood coagulation, and soluble fibrin; a hybridoma; and an immunoassay for detecting the initial stage of blood coagulation with high sensitivity, quickly, using the monoclonal antibody. Using a fibrinogen analog in blood as an immune source, cell fusion is carried out to prepare a monoclonal antibody which is not reactive with fibrinogen and is specifically and simultaneously reactive with a native fibrin monomer (that is, a fibrin monomer which is present in a body fluid, in particular in blood, and is not solubilized) and soluble fibrin. The fibrin monomer analog is preferably fibrinogen treated with bathroxobin, which is a snake venom.Type: GrantFiled: February 17, 1999Date of Patent: September 17, 2002Assignee: Nissui Pharmaceutical Co., Ltd.Inventors: Seiji Tanaka, Akiei Hamano, Mamoru Umeda

Patent number: 6444433Abstract: We have produced a hybridoma cell line that produces monoclonal antibodies (MAb) that bind effectively to 2-methylisoborneol (MIB). The MAbs were produced using a structurally related molecule, borneol, whose structure was minimally changed when complexed to the protein carrier. These MAbs detected MIB at approximately 0.01 to 1 ppb (or lower) when used in ELISA assays. Because these antibodies were produced as MAbs, their affinity characteristics remained constant. With access to MAb's, MIB can be easily detected at low levels using immunological techniques that are adapted to fast and easy field assays of large samples. For example, catfish could easily be assayed in the field for the presence of MIB prior to marketing.Type: GrantFiled: January 24, 2000Date of Patent: September 3, 2002Assignee: Board of Supervisors of Louisiana State University and Agriculture and Mechanical CollegeInventors: Leslie C.

Patent number: 6433148Abstract: The present invention describes the selection and use of antidiotypic monoclonal antibodies. (AB2) IgG type with the main characteristic of being highly connected to the idiotipic network and recognition of B and T human lymphocytes, which are major participants in the immune response. According to the previous statement the objective of this invention is to provide antidiotypic monoclonal antibodies IgG type connected to the immune network, able to interact with T and B lymphocytes and able to exert an immunoregulatory effect, irmunostimulation or immunosupression that can be used for immunotherapy of autoimune diseases, infectious diseases and cancer.Type: GrantFiled: November 17, 1997Date of Patent: August 13, 2002Assignee: Centro de Immunologia Molecular (CIM)Inventors: Amparo Emilia Macias Abrahan, Rolando Perez Rodriguez, Teresita Rodriguez Obaya, Mercedes Ramos Zamora, Gumersinda Bombino Lopez, Orlando Pena Marichal
