| Description: | A549 cells (originally derived through explant culture from a 58 year old male's carcinomatous lung tissue) are seeded into the inner 60 wells of a 96-well plate at 3,000 cells per well in a volume of 50 μL using A549 growth media (F-12K Media, 1% Penn/Strep, 1% nonessential amino acids, 10% heat-inactivated FBS). 2-fold serial dilutions of control and test compounds are added to the wells in duplicate in a total volume of 25 μL. Viral stock is then added to the wells at a multiplicity of infection (MOI) of 0.5 in a volume of 25 μL, bringing the total volume of each well to 100 μL. The MOI is calculated using the PFU/mL, or TCID50 if unavailable. Each 96-well plate has a control column of 6 wells with cells and virus but no compound (negative control, max CPE), a column with cells but no compound or virus (positive control, minimum CPE), and a column with no cells or virus or compound (background plate/reagent control). The control wells with cells but no virus are given an additional 25 μL of growth media containing an equal quantity of sucrose as those wells receiving the viral stock in order to keep consistent in media and volume conditions. The outer wells of the plate are filled with 125 μL of moat media (DMEM, 1% Penn/Strep) to act as a thermal and evaporative moat around the test wells. 6 days post infection, the plates are read using qPCR or ATP lite (50 μL added per well), which quantifies the amount of ATP (a measure of cell health) present in each well. Assay plates treated with APTlite are read using the Envision luminometer. |
