A human monoclonal antibody against HLA-A25.

We are reporting the production and characterization of a human monoclonal antibody recognizing antigen HLA-25. The antibody was developed by a line transformed in vitro by the Epstein-Barr virus. The immune B lymphocytes for transformation were generated by planned immunization of a volunteer with repeated doses of allogenic peripheral blood lymphocytes of one donor over the course of 7 years. The antibody showed correlation with A25 antigen on a panel of 244 individuals tested by microcytotoxicity. The antibody showed neither cytotoxic reactivity nor CYNAP phenomenon with antigens of HLA-10 CREG.
