摘要:
A liposome immunoassay comprising the steps of reacting an analyte antigen, a liposome bearing antibody comprising a first antibody to the analyte antigen and a liposome encapsulating a marker therein linked to the antibody, and a second antibody to the analyte antigen to form an antigen-antibody complex, releasing the marker from the liposome in an amount depending on an amount of the analyte antigen in the presence of a complement, and measuring the released marker to determine the analyte antigen, characterized in using a third antibody capable of binding directly or indirectly to the second antibody and having an ability to activate the complement; andA kit for liposome immunoassay comprising at least one of; (1) an liposome bearing antibody comprising a first antibody to an analyte antigen and liposome encapsulating a marker therein linked to the antibody; (2) a second antibody to the analyte antigen; (3) a third antibody capable of binding directly or indirectly to the second antibody and having an ability to activate a complement; and (4) the complement.
摘要:
A method of quantitation of human pulmonary surfactant characterized by determining the quantity of human pulmonary surfactant in the test sample according to the immunological method by use of the primary monoclonal antibodies which recognize the human pulmonary surfactant apoproteins and the labeled secondary monoclonal antibodies which recognize said apoproteins but bind to a part of the antigen which is different from the one to which the primary monoclonal antibodies bind, and a reagent kit to be used for the quantitation.
摘要:
A standard material for measuring immune complexes which is prepared by chemically binding immunoglobulin and/or its fragment with a complement and/or its derivative through the medium of a bifunctional reagent. By using the standard material, the standard curve which is used for measuring immune complexes existing in the blood is obtained.
摘要:
A method of immunologically determining human acid glutathione S-transferase in a human assay sample, which comprises bringing the assay sample into contact with a first antibody bound to an insoluble solid carrier and a labelled second antibody, either the first or second antibody being a polyclonal antibody capable of recognizing human acid glutathione S-transferase or an equivalent fragment of the polyclonal antibody, and the other antibody being a monoclonal antibody capable of specifically recognizing human acid glutathione S-transferase or an equivalent fragment of the monoclonal antibody, a method of diagnosing cancer in a human digestive organ by using the above method, a reagent therefor, a kit therefor and a monoclonal antibody for use therein.
摘要:
An immunoassay method performed in solution wherein a protein having an average molecular weight of 16,000 to 50,000 and an isoelectric point of 1.0 to 5.0 or a mixture containing the same is permitted to exist as the antigen-antibody reaction controller in the immunoreaction solution, and the final concentration of the antigen-antibody controller in the immunoreaction solution is controlled to 0.02 to 0.9% by weight, and a reagent kit to be used for an immunoassay containing the above antigen-antibody reaction controller at a final concentration of 0.02 to 0.9% by weight in the immunoreaction solution, as a part of the constituents thereof.
摘要:
A monoclonal antibody for human acid glutathion S-transferase. This monoclonal antibody can be utilized as a diagnostic for cancers such as cancer of liver, gastric cancer, and cancer of the blood.
摘要:
A reagent for measuring immune complexes fixed with an anti-C3 antibody Facb fragment. By using the reagent, immune complexes existing in the blood serum or body fluid are quantitatively measured.
摘要:
A method of immunologically assaying intact human osteocalcin in a human assay sample is provided by using an antibody having an epitope in a region of an amino acid sequence 1 to 20 on the N-terminal side of human osteocalcin and an antibody having an epitope in a region of an amino acid sequence 36 to 49 on the C-terminal side of human osteocalcin. A reagent and a kit therefor are provided. Furthermore, a method of immunologically assaying the total amount of human intact osteocalcin in a human assay sample, and a reagent and a kit therefor are also provided. A monoclonal antibody and a polyclonal antibody are used for the assay. A process for producing these antibodies, and utilization of these antibodies is described.
