2.6.2 Materials
for Quantification
of Baculoviruses Using
a Viral Plaque Assay
1. Spodoptera frugiperda cell suspension with a cell density of
1.0 Â 10
6 cells/mL (e.g., Sf-9 Insect Cells, Merck, Darmstadt,
Germany).
2. Insect cell culture medium (e.g., Sf900 II, Thermo Fisher
Scientific, Waltham, MA, USA).
3. Generated P2 virus stock.
4. 4% agarose Gel (e.g., Plaque agarose, Biozym Scientific, Hessisch Oldendorf, Germany).
