Abstract: | Three hybridoma cell lines producing monoclonal antibodies (MAbs) against LSCC-BK3 cells which are susceptible to infectious bursal disease virus (IBDV) infection were produced and characterized. The MAbs, designated T7, Q11 and Q13, inhibited the attachment of IBDV to LSCC-BK3 cells. Furthermore, these MAbs bound to LSCC-BK3 but not to nonpermissive cells in flow cytometry. MAb T7 detected a 110-kDa membrane protein of LSCC-BK3 cells, whereas Q11 and Q13 reacted with membrane proteins of molecular weights 58-, 85-, 90- and 110-kDa. These observations imply that the 110-kDa protein recognized by all the MAbs is associated with IBDV binding. The MAbs established in this study are useful for studying the interaction between IBDV and its target cell. |
