Monoclonal antibodies capable of recognizing n-acetylneuraminic acid in beta-arrangement used for diagnosis and prognosis of tumors and acute inflammatory diseases

摘要

A hybridoma producing a monoclonal antibody specific to N-acetylneuraminic acid or a derivative thereof in the beta-arrangement as an epitope or antigenic determinant is herein disclosed. The monoclonal antibody produced by the hybridoma can be used in clinical purposes such as diagnosis and/or prognosis of a certain kinds of cancers and acute inflammatory diseases. The hybridoma can be generated by fusing (i) B cells or lymphocytes obtained by immunizing an animal with an N-acetylneuraminic acid or a derivative thereof in beta-arrangement as an antigen and (ii) myeloma cells.
