Disclosed are an antibody which have a binding activity to human betacellulin protein or a mutein thereof with specificity; especially a monoclonal antibody which does not have cross reactitivity with human epidermal growth factor (EGF) and human transforming growth factor a (TGF-α), belongs to the immunoglobulin class of IgG, and,specifically binds to human betacellulin protein to neutralize biological activity thereof; a hybridoma for producing the monoclonal antibody; and a method for producing the monoclonal antibody. Said monoclonal antibody neutralizes biological activity of a human BTC protein, and bind to the protein with high sensitivity and specificity, so that they can be used as a therapeutic agent for diseases such as arterial sclerosis and cancers, and also used as a reagent for assaying the human BTC protein or a mutein thereof and as a diagnostic agent for diabetes or complications thereof.
A monoclonal antibody which (a) specifically binds to a human betacellulin protein comprising the amino acid sequence of SEQ ID NO:1, (b) specifically recognizes amino acid 31 (Arg) to amino acid 80 (Tyr) of SEQ ID NO:1, (c) neutralizes the cell growth stimulating activity of the human betacellulin protein, (d) does not cross-react with at least human epidermal growth factor, human transforming growth factor a, or mouse betacellulin protein, (e) belongs to the immunoglobulin class of IgG, and (f) is produced by cell lines, Mouse 1A1 (FERM BP 5393), Mouse 2B2 (FERM BP 5394) or Mouse 5E5 (FERM BP 5395).
