- Luciferase activity assay
Luciferase activity assay - time point 1
Cell prep
- Harvested cells
- Seeded new dox+ plate with 1/2 of cells
- Pelleted other half, resuspended in 2 mL FACS buffer
Assay reagents
- Used the Biotium Steady-Luc Firefly HTS Assay Kit
- Thawed reagents to room temp
- 6 experimental samples x 3 repliates = 18 assays (one time point)
- Need 100 μL complete steady-luc buffer per assay = 1800 μL complete steady-luc buffer
- Dissolved dry D-luciferin to make 50x stock by adding 80 μL dH2O to the vial
Luc assay
- Filtered 500 μL cells through strainer caps (should use 700 μL next time)
- Transferred 100 μL strained cells to 3 wells in 96-well plate (black walls; clear, flat bottom)
- Saved remainder of strained cells for flow cytometry/ counting
- Made 2000 μL complete steady-luc buffer: Added 40 μL 50x D-luciferin to 2 mL buffer
- QUICKLY Added 100 μL of complete steady-luc buffer to each sample (pipetted up/down once to mix)
- Incubated at room temp/ 10 min.
Cell count
- Wang lab's Accuri flow cytometer. Set machine to sample 2 uL of cells
