Monoclonal antibodies to baculovirus structural proteins: determination of specificities by Western blot analysis.
Conventional mouse hybridoma technology was utilized to produce a panel of monoclonal antibodies which reacted with baculovirus proteins. Using an enzyme-linked immunosorbent assay (ELISA), the hybridomas which were raised against polyhedrin from Autographa californica nuclear polyhedrosis virus (AcNPV) and Choristoeura fumiferana nuclear polyhedrosis virus (CfNPV) were found to cross-react differentially with polyhedrins and granulins from several species of baculoviruses. Hybridoma antibodies which reacted against the nonoccluded form ( NOV) of AcNPV in an ELISA test expressed different specificities for the occluded form of the virus (OV), a mutant strain of AcNPV, and CfNPV. Four hybridoma clones produced antibody which neutralized the infectivity of AcNPV NOV. One hybridoma antibody reacted strongly with the uninfected Spodoptera frugiperda host cell line. Using Western blot analysis, it was shown that hybridoma antibodies against polyhedrin reacted differentially with the complete polypeptide and protease-generated fragments of polyhedrin. The polypeptide specificity of 19 of 28 hybridoma antibodies which reacted with OV and NOV of AcNPV was assigned using Western blot analysis.[1]References
