| Research Abstract |
The present study aimed at developing a novel assay method using a baculovirus (BV)-host cell binding for the determination of BV titer. First, we constructed recombinant BV displaying either GST or EGFP on GP64 envelope protein in order to distinguish between infected and uninfected cells. However, the protein probes displayed on BVs were not sensitive enough to use for this purpose. In addition, it was so difficult to produce the recombinant BVs because of their high susceptibility to endogenous proteases. Second, we examined the BV-host cell binding conditions to separate active and inactive BVs. As a result, it was suggested that the BV-host cell binding was applicable to the BV titer determination by combining with real-time PCR.
