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 osteocalcinand an antibody having an epitope in a region of an amino acid sequence 36 to 49 on the C-terminal side of human osteocalcin. Furthermore, a method of immunologically assaying the total amount of human intact osteocalcin in a human assay sample is provided. A reagent and a kit therefor are also described, as well as a monclonal antibody and a polyclonal antibody used for the assay a process for producing these antibodies; and a process for use of these antibodies.

A method for determining chondrocalcin through an immunoassay using an enzyme(s)-labeled mammalian chondrocalcin or enzyme(s)-labeled anti-chondrocalcin antibody which is characterized by that mammalian body fluid is used as a specimen and immunoreaction in a solution is utilized to determine the chondrocalcin of the mammalian, reagents and a kit therefor. This determination can be utilized for diagnosis or the like for cartilage-relating diseases in mammals.

Method for determining chondrocalcin

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.

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.

Quantitation of human pulmonary surfactant and reagent kit to be used

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.

Reagents for measurement of immune complexes and method for measurement

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.
