A plasmid pAc373GM-CSF was constructed and co-transfected into Spodoptera frugiperda (Sf9) cells with wild-type Autographa californica nuclear polyhedrosis virus (AcNPV) DNA. The recombinant virus vAc373GM-CSF was identified and purified by several rounds of plaque hybridization. By assaying the culture medium, we demonstrated recombinant virus infected Sf9 cells expressing hGM-CSF. Recombinant hGM-CSFs with apparent molecular masses of 14.5, 15.5 and 16.5 kDa were detected by the Western blot method. All 3 forms have biological activity of hGM-CSF. Following N-glycanase treatment, a single band of 14.5-15.5 kDa appeared in SDS-PAGE. Western blot analysis of expression in Sf9 cell treated with tunicamycin revealed only the presence of the 14.5 kDa species. Thus, the signal sequence of recombinant hGM-CSF could be recognized and cleaved by infected insect cell and the resultant molecule secreted into the media.
