Treatment Conditions
Chemical treatment is required for detection of endogenous citrullinated proteins in cell lines. PADs (including PADI2 and PADI4) are the enzymes that hydrolyze arginine to citrulline, in the presence of Ca2+ and ionomycin. Please refer to PMID: 26360112
Controls:
- Mock (no transfection)
- Transfection reagent–only control
- Empty vector control
- Vehicle control for chemical treatment
Generation of PADI2 or PADI4 overexpression cell line and treatment with CaCl2/Ionomycin
1. Prior to transfection with PADI2 or PADI4 expression vector, seed cells in complete medium and place in a 37ºC, 5% CO2 incubator for 24 hours or until cells reach 70-80% confluence.
For a single T-175 flask we recommend seeding the following common cell lines as follows in 30 mL media:
- HEK-293T: 1x107 cells
- MCF7: 2.5-4x106 cells
- NIH3T3: 4-5x106 cells
- C6: 3-4x106 cells
2. Once cells have reached confluence, prepare the PADI2 or PADI4 expression vector for transfection using your preferred method (PMID: 33976969).
3. 24-48 hours after transfection, remove the medium from the cells and replace with fresh complete medium containing 10 mM CaCl2 (ab285384) and 10 uM Ionomycin (ab120116) and incubate for 2-4 hours.
Key Considerations:
- For alternative cell lines, you should confirm the transfectability, growth rate, and sensitivity of the cell line to the planned chemical treatment. Incubation times and treatment length may need to be adjusted.
