Preparation of a bovine monoclonal antibody to testosterone by interspecies fusion.
This communication reports the first successful attempt to produce a hybridoma cell line secreting bovine immunoglobulin to a small hapten, starting with peripheral blood lymphocytes, rather than spleen or lymph node cells. A heteromyeloma line, sensitive to selective media, was made by fusing NS1/1-Ag4-1 mouse myeloma cells with bovine peripheral blood lymphocytes. This cell line was then fused with blood lymphocytes from a steer immunised with a testosterone immunogen. Cell cultures were screened using an ELISA specific for bovine antibodies to testosterone. Following repeated cloning, a cell line was established which secretes moderate levels of a specific, high affinity antibody to testosterone. This particular cell line has significant potential for veterinary application and the successful fusion demonstrates the possibilities of heteromyelomas for the development of non-murine monoclonal antibodies.
