Abstract
This chapter outlines a rapid detection method to determine the virus titer of yourbaculovirus stock. Staining of cells with fluorescently labeled gp64 antibody allows for flow cytometer-based quantitation of baculovirus-infected insect cells. In this assay, Sf9 cells are infected with tenfold serial dilutions of the test virus stock, and baculovirus titers are calculated based on the ratio of infected to uninfected cells 13 to 18h after inoculation.
