• | 96-well microliter plates |
Procedure:
1. | Day 1: Seed H1299 cells at a density of 5 x 105 cells/well into each well of 6-well plates containing DHGFi5. |
2. | Incubate cell culture plates at 37°C and 5% CO2) for 24 hours, until approximately 75% cell confluency. |
3. | Day 2: Incubate aliquots of the undiluted Ad vector at 37°C for 5 minutes and for 30 minutes. An undiluted aliquot of the Ad vector will be kept at room temperature before dilution. |
4. | Dilute each of the adenovirus test articles pre-incubated in step 3. The adenovirus stock solution should he prepared by dilution with DHGFi5. The concentrations of the Ad stock solutions and the dose range will be determined after virus titers are available. |

5. | Carefully remove cell culture medium without detaching the adherent cells in each well. |
6. | Pipette 0.5 ml of each Ad dilution or plain medium into each well Each Ad concentration should be tested in triplicate (3 xxxxx in the culture plate). The last 3 xxxxx should receive 0.5 ml of DHGFi5 per well to serve as a negative control. |
7. | Incubate the cell culture plate at 37°C and 5% CO2 for 1 hour. |
8. | Add 2 ml of DHGFi5 to each well and continue to incubate the plate at 37°C and 5% CO2 for an additional 23 hours. |
9. | Carefully remove cell culture medium without detaching the adherent cells in each well. Then, rinse cells with 2 ml Versene (PBS-EDTA) or PBS. |
10. | Add 0.5 ml of a 0.25% solution of trypsin-EDTA to each well. After the cells become non-adherent, add 0.5 ml of DHGFi5 per well to neutralize the trypsin. |
11. | Pipette each well of cells into a centrifuge tube and centrifuge gently to pellet the cells. |
12. | Remove the supernatent from each tube and gently resuspend each cell pellet in 1 ml DPBS. |
13. | Centrifuge gently to pellet the cells and remove the supernatent. The cell pellets may be used immediately or stored at £ -60°C for up to 1 month. |
14. | Lyse each cell pellet using a mixture of cell lysis buffer and protease inhibitor cocktail. |
15. | Using a microfuge, centrifuge down the cell debris, then collect the supernatants into clean test tubes for analysis in the p53 pan ELISA assay kit. Follow the manufacturer’s instructions. An overview follows: |
16. | The sample derived from the negative control cells is diluted 1 in 100 with the Dilution Buffer in the assay kit and an aliquot of this diluted negative control is used to prepare a p53 standard spiked negative control by the addition of 300 µl of the spiked negative control and 100 µl. of Solution 2f from the assay kit. |
17. | A p53 standard curve is derived from Solutions 2a through 2f of the assay kit. |
18. | The samples deriving from the test article and the adenovirus-transduced cells are diluted 1 in 1000, 1 in 2000, and 1 in 4000 with the Dilution Buffer. |
19. | A 100 µl aliquot of all samples, controls and standards are loaded in triplicate into xxxxx of a 96-well microtiter plate and 100 µl of the Incubation Buffer (Solution 7 of the assay kit) is added to each well. The plate is covered and incubated at room temperature for 2 hours on an orbital shaker. |
11

20. | After this 2 hour period, the Incubation Buffer is removed and the xxxxx washed 5 times with 300 µl of Wash Buffer (Solution 4 of the test kit). |
21. | After this, 200 µl of the Substrate Solution (Solution 5 of the test kit) is added to each well and the plate is covered and incubated at room temperature on an orbital shaker for between 10 and 20 minutes. |
22. | After this period, 50 µl of the Stop Solution (Solution 6 of the test kit) is added to each well and mixed by pipetting. |
23. | The intensity of color formed from the Substrate Solution is proportional to the amount of p53 protein present and is determined by a plate reader. The level of p53 protein produced by the cells is read directly off the standard curve. |
