摘要:
A recombinant herpes virus is provided which efficiently expresses an exogenous protein of interest in an inoculated animal host to thereby endow the host with excellent immunization. A recombinant herpes virus which incorporates an exogenous gene expression cassette in which a herpes virus-derived gB gene (a gene homologous to herpes simplex virus gB gene) promoter is used as a promoter for expression of an exogenous gene.
摘要:
A novel peptide obtained from Haemophilus paragallinarum has been found useful for preventing avian infectious coryza. This polypeptide induces production of hemagglutination-inhibition antibody and prevents infection and onset of avian infectious coryza. The invention further provides a gene coding for the polypeptide, a recombinant vector for expression of this gene, a host transformed with this vector, a process for preparing the polypeptide in a host, a vaccine for avian infectious coryza comprising the polypeptide as an active ingredient, a monoclonal antibody obtained using the polypeptide as an immunogen, and a diagnostic agent and a therapeutic agent for avian infectious coryza using the peptide and the antibody.

摘要:
Shuttle vectors including a DNA sequence of the yeast Saccharomyces cerevisiae including ars 1.2 micron ori and a marker gene for transformed yeast permitting synthesis of leucine by the transformant; adjacent to said ars 1 a DNA sequence of Escherichia coli which is either in EcoR1--PvuII or EcoR1--TthIII--I fragment of plasmid pBR322; and adjacent to the yeast marker gene the expression control region of the repressible acid phosphatase gene of yeast.
摘要:
Antisense oligonucleotides are provided which are complementary to and hybridizable with at least a portion of HCV RNA and which are capable of inhibiting the function of the HCV RNA. These oligonucleotides can be administered to inhibit the activity of Hepatitis C virus in vivo or in vitro. These compounds can be used either prophylactically or therapeutically to reduce the severity of diseases associated with Hepatitis C virus, and for diagnosis and detection of HCV and HCV-associated diseases. Methods of using these compounds are also disclosed.

摘要:
A method for purification of HBs antigen, which comprises treating an HBs tigen-containing material with an acid, optionally subjecting to salting out with ammonium sulfate, and subjecting the material to a chromatography with hydroxyapatite, by which a highly purified HBs antigen suitable for the preparation of HBV vaccine or diagnostic agent can be obtained in an industrial scale. This method is particularly useful for the purification of HBs antigen-containing material produced by recombinants obtained by DNA recombination technique.
摘要:
A method for the purification of HBc antigen, particularly HBc antigen produced by recombinant organisms by means of DNA recombination technique, which comprises subjecting a solution containing HBc antigen to acid-treatment, wherein the solution containing HBc antigen is acidified to a pH range of not higher than 6 by adding an acid and then resulting precipitates of lipid and contaminant proteins are removed, and then subjecting the acid-treated solution containing HBc antigen to an ion exchange chromatography with an anion exchanger, and a method for measuring HBc antibody by using said purified HBc antigen in a passive hemagglutination method, EIA method or RIA method.
摘要:
Industrially useful method for the purification of HBs antigen produced by a recombinant organism being capable of producing HBs antigen which is prepared by means of DNA recombination technique, which comprises subjecting an HBs antigen-containing material produced by a recombinant organism to an adsorption chromatography with a silica, optionally followed by a gel filtration and further an adsorption chromatography with a hydroxyapatite, and then eluting the HBs antigen, preferably, with a buffer having a pH 9 or more which is incorporated with urea. The purification method can give a highly pure HBs antigen suitable for the preparation of hepatitis B vaccine in a large scale from recombinant organisms prepared by DNA recombination technique.
