Production and characterization of a monoclonal antibody to biotin.


Monoclonal antibodies to biotin have been prepared by using biotin linked to keyhole limpet haemocyanin (KLH) as the antigen. Spleen cells obtained from mice immunized with biotin-KLH were fused with the myeloma cell line NS-1. The resulting hybridomas were screened for the production of antibodies to biotin using an enzyme-linked immunosorbent assay. Clones producing antibodies to biotin were isolated by limiting dilution methods. Four cell lines, each derived originally from a different fusion, were chosen for the production of monoclonal antibodies. The monoclonal antibodies obtained have been characterized with respect to their ability to interact with biotin, biotin-bovine serum albumin, biotin-KLH and biocytin as well as to inhibit biotin-dependent enzymes. They have been used to produce cellular biotin deficiency in vitro for studies of biotin function.
