Virus Plaque Assay: A Technique to Measure Infectious Herpes Simplex Virus via Quantification of Plaques Formed in Monolayer of Virus-Infected Cells

プロトコル

1. Seeding of the Vero cells

1. The day before initiating the plaque assay, trypsinize Vero cells and resuspend them in regular Dulbecco's Modified Eagles Medium (DMEM) and supplement as per standard cell culture methodology. Resuspend the trypsinized cells in 10 mL of DMEM per T-75 flask of the confluent Vero cells (~10⁷ cells).
   NOTE: DMEM is used for plaque assays instead of alpha-MEM because it slightly slows the cell growth rate and favors better plaque assay results.
2. Count the cells by one's preferred method (e.g., a standard hemocytometer with Trypan Blue exclusion).
3. Seed the cells at 4 x 10....
