    摘要: A method of diagnosing metabolic bone diseases, especially osteoporosis and arthrosis characterized by determining the concentration of osteoclastgenesis inhibitory factor (OCIF) in humor. Monoclonal antibodies recognizing equally both of monomer type and dimer type of OCIF. Monoclonal antibodies recognizing selectively dimer type of OCIF. And to provide an assay kit for determination of OCIF concentration comprising the aforementioned two antibodies recognizing different epitope of OCIF and having high affinity showing dissociation constant of less than 2×10−7 M with antigen. It is useful for a method of diagnosing metabolic bone diseases, especially osteoporosis and arthrosis or for an assay reagent for research thereof.

    摘要: A protein is provided derived from human fibroblast having an N-terminal amino acid sequence represented by SEQ ID NOS: 1 and 2, having a molecular weight of approximately 15kD under reducing and non-reducing conditions by (dosium dodecyl sulfate-polyacrylamide gel electrophoresis), and having an activity to stimulate growth of osteoblast. The protein is produced by gene engineering procedures, contains the amino acid sequence represented by SEQ ID NO: 9 and has osteoblast growth activity. Also provided is a method for preparing the protein by culturing human fibroblast and treating the conditioned medium for purification. The protein is utilized for the treatment of diseases characterized by decreased bone mass such as osteoporosis or is utilized as an antigen for immunological diagnosis of diseases.
