Simultaneous raising of rabbit monoclonal antibodies to fluoroquinolones with diverse recognition functionalities via single mixture immunization

Highly specific monoclonal and polyclonal antibodies are the key components in a diverse set of immunoassay applications, from research work to routine monitoring and analysis. In the current manuscript, combinatorial strategies for a single mixture immunization, screening and rabbit hybridoma cell technology were described. Fluoroquinolones (FQs) drugs were chosen as representative analytes. Six FQs were conjugated with bovine serum albumin and used as immunogens for subsequent immunization, while a mixture of all was injected for coimmunization. The hybridomas obtained against the individual and multiple FQs were used for the production of diverse varieties of rabbit monoclonal antibodies (RabMAbs) against the target analytes. As was proven by indirect competitive ELISA and quantitative lateral flow immunoassay, this approach opens a new way for simultaneously obtaining functional monoclonal antibodies which are capable of recognizing both individual and multiple analytes in a single preparation circle. This addresses various needs of different monitoring regulations as analytical methodology advances.Highly specific monoclonal and polyclonal antibodies are the key components in a diverse set of immunoassay applications, from research work to routine monitoring and analysis.
