Abstract:
PROBLEM TO BE SOLVED: To provide a highly specific and novel monoclonal antibody available for detecting a hepatitis C virus protein. SOLUTION: A monoclonal antibody not binding to hepatitis C virus C-100 protein and hepatitis C virus 33C protein and specifically binding to hepatitis C virus core protein, a hybridoma yielding the monoclonal antibody, a method for using the monoclonal antibody and an assay kit containing the antibody are provided.
Abstract:
PROBLEM TO BE SOLVED: To obtain an antibody excellent in assay accuracy ad useful for diagnostics, kits, vaccines, etc., by setting against hepatitis GB virus(HGBV) epitope(s). SOLUTION: This antibody is such one as to stand against at least one kind of Hepatitis GB virus(HGBV) epitope, being pref. a polyclonal or monoclonal antibody. This antibody is obtained by administering an individual with an isolated immunogenic polypeptide (or a fragment thereof) containing at least one HGBV epitope at an amount enough to induce immune response. Furthermore, it is preferable that a suspectable test sample containing HGBV is contacted with an antibody (fragment) specifically bindable to at least one HGBV antigen for an enough time and under sufficient conditions to form an antibody/antigen complex to detect an antibody-contg. complex to detect a HGBV antigen in the test sample.
Abstract:
PROBLEM TO BE SOLVED: To provide an antibody specifically bonding generally to hepatitis C virus(HCV), more particularly, a panel of a new hybridoma cell strain secreting a monoclonal antibody against HCV protein 33C and the use of the monoclonal antibody. SOLUTION: The present invention relates to a monoclonal antibody specifically bonding to HCV protein 33C and free from bonding potency to HCV protein C-100 and a core and to a hybridoma producing the monoclonal antibody and selected from the group consisting of A.T.C.C. deposit No. HB10594, HB10589, HB10607 and HB10600. It also relates to a method for the use of the monoclonal antibody e.g. for the detection of hepatitis C virus HCV 33C protein in a specimen and an assay kit containing the antibody.
Abstract:
PROBLEM TO BE SOLVED: To obtain an HIV transmembrane antigenic polypeptide capable of increasing the expression in heterologous expression systems and useful e.g. for the diagnosis and treatment of AIDS by including a specific amino acid sequence. SOLUTION: This HIV transmembrane antigenic polypeptide is such one as to have an amino acid sequence of formula I. This HIV transmembrane antigenic polypeptide is obtained by culturing host cells such as E. coli, transformed by a recombinant expression vector integrated with a synthetic gene having a DNA sequence of formula II and encoding the HIV transmembrane antigenic polypeptide.
Abstract:
The invention relates to hepatitis GB virus C. nucleic acids, more particularly to oligonucleotide probes and primers for use in the detection of genotypes of hepatitis GB virus C.
Abstract:
Mammalian expression systems for the production of HCV E1-E2 fusion proteins. Such expression systems provide high yields of HCV proteins extracellularly, and enable the development of diagnostic, vaccine and therapeutic reagents which contain glycosylated structural antigens and also allow for the isolation of the HCV etiological agent.
Abstract:
Hepatitis GB Virus (HGBV) nucleic acid and amino acid sequences useful for a variety of diagnostic and therapeutic applications, kits for using the HGBV nucleic acid or amino acid sequences, HGBV immunogenic particles, and antibodies which specifically bind to HGBV. Also provided are methods for producing antibodies, polyclonal or monoclonal, from the HGBV nucleic acid or amino acid sequences.
Abstract:
The present invention relates to nucleic oligomer primers or probes useful for detection of TTV in test samples. Also provided are assays which utilize these primers and probes, as well as test kits which contain these oligomer primers and/or probes. In addition, the present invention encompasses the use of TTV nucleotide sequences as nucleic acid vectors and as markers for determining transmission between individuals as well as the route thereof. Additionally, the present invention encompasses a method of detecting TTV infection prior to xenotransplantation of a tissue or organ.
