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

The MAbs established in this study are useful for studying the interaction between IBDV and its target cell. KEY WORDS: binding, infectious bursal disease virus, monoclonal antibody.
