ANTIBODY AND USE OF THE SAME

摘要

It is intended to provide an antibody by which metastin or its derivative ca n be sensitively and specifically quantified; a method of detecting and quantifying metastin or its derivative using the antibody; and diagnostics (for example, a diagnostic for pregnancy) using the same. More specifically speaking, an antibody specifically reacting with a peptide fragment in the N - terminal or C-terminal side of a polypeptide having the amino acid sequence represented by SEQ ID NO:1 or its derivative; a method of detecting and quantifying metastin or its derivative using the antibody; and diagnostics using the same.
