摘要:
A hepatitis A,B-combined adjuvanted vaccine is disclosed in this application, said vaccine comprising an inactivated hepatitis A virus antigen, a hepatitis B virus surface antigen and an adjuvant. The present vaccine is obtained by causing the antigens to be adsorbed to the adjuvant. According to the present invention, the infection with not only hepatitis A virus but also hepatitis B vrius can be prevented without causing any interference due to the mixing of these antigens and any severe side-effects, and the anti-hepatitis A virus antibody titer is greatly enhanced by the mixing.
摘要:
Described are novel chimeric anti-human immunodeficiency virus (HIV) antibodies which comprise a constant region derived from human antibody and variable region derived from mouse monoclonal antibody, gene fragments coding for the variable region the H and L chain of chimeric anti-HIV antibodies which are effective for expression of chimeric anti-HIV antibodies having an HIV-neutralizing activity, a transformant where such gene fragments are incorporated, chimeric anti-HIV antibodies expressed therefrom and a process for their preparation. The chimeric anti-HIV antibodies of the present invention show anti-HIV neutralizing activity and are useful for the diagnosis, treatment and prevention of acquired immunodeficiency syndrome (AIDS) caused by HIV without side effects such as anaphylactic shock or serum sickness.
摘要:
The present invention provides novel spherical grains of polyamino acid which can be used as a filler in chromatography, cosmetic powder and the like. The spherical grains can be produced by a method which comprises the steps of preparing a solution of hydrophobic polyamino acids, such as poly n-leucine, dissolved in an organic solvent; adding the solution to an aqueous medium and agitating said medium so as to obtain a dispersion of the spherical grains of the polyamino acid dispersed in the aqueous medium while evaporating the organic solvent; and isolating the spherical grains of the polyamino acid from the dispersion.
摘要:
Disclosed are monoclonal antibodies to the HBsAg which are prepared by forming hybridomas between human peripheral blood lymphocyte cells, derived from humans having high titers of anti-HBsAg antibodies, and myeloma cells, cloning the hybridomas and selecting the antibody-producing clones. The monoclonal antibodies react with all the subtypes of the HBsAg and are very effective in diagnosis and treatment of diseases due to the viral infection.
摘要:
Described is a highly sensitive immunoassay method for determining the amounts of TSH contained in body fluids, in which an anti-β-subunit TSH monoclonal antibody having a specific association constant value is used.
摘要:
A live vaccine for infectious laryngotracheitis, which comprises culture cells infected with attenuated infectious laryngotracheitis virus. Also, a live combined vaccine for infectious laryngotracheitis and Marek's disease, which comprises culture cells infected with attenuated viruses of these two diseases. These vaccines can be used on day-old (newborn) chicken, by subcutaneous or intramuscular injection, to give them immunity from infection by the virus or viruses.
摘要:
Disclosed is an improved method for the purification of Japanese encephalitis virus, which comprises subjecting a solution containing the Japanese encephalitis virus to column chromatography using, as a gel for chromatography, a sulfuric acid ester of cellulose or a crosslinked polysaccharide. The method can provide highly purified Japanese encephalitis virus, which is useful for obtaining an effective vaccine against Japanese encephalitis.
摘要:
Described is a method for producing highly pure LPF-HA (Leucocytosis-promoting Factor Hemagglutinin) from culture media of Bordetella pertussis in a high yield by an affinity chromatography using a denatured ceruloplasmin as a ligand. The LPF-HA obtained by this invention is highly pure and contains almost no endotoxin of B. pertussis and is useful for the preparation of various reagents utilizing the physiological activities, of a medicine for treating diabetes and of a pertussis vaccine.
摘要:
Disclosed is a potential-causing element, in the form of an electrode or a membrane, for use in immunosensors, which comprises a polypyrrole or polythiophene film bound with an antigen or an antibody. The potential-causing element can be prepared in an easy manner through electrolytic polymerization of pyrrole or thiopene so as to control the thickness of the polymer film which will develop desired immunosresponse characteristics.
摘要:
Disclosed are certain animal sera and ascites that are useful for inhibiting the nonspecific-reactions occuring when carrying out an immunological assay with monoclonal antibodies (MCA). The use of the inhibitor makes the assay very accurate.
