This study was performed to produce monoclonal antibodies to the major polyhedral inclusion body (PIB) antigen of the occluded form of Hyphantria cunea nuclear polyhedrosis virus (HcNPV). PIB proteinS were purfied from the Spodoptera frugiperda cell infected with HcNPVs. Using the purified PIB protein, BALB/C mice were immunized 3 times with 2 weeks intervals. The spleen were removed and fused with Sp2/0-Ag14, mouse myeloma cells.

The effect of AcNPV infection conditions such as serum concentration, pH, CaCl2, lysosomotropic agent, cell density at infection, agitation, aeration and nutritional supplementattion on recombinant protein production in Spodoptera frugiperda 21 cells was investigated using tissue culture flask, bottle and spinner flask. It was shown that serum, CaCl2, pH and cell density at infection affected recombinant production. The lysosomotropic agent did not significantly influence recombinant protein production.
