Cell Activation Cocktail (without Brefeldin A) is a pre-mixed cocktail with optimized concentration of PMA (phorbol 12-myristate-13-acetate) and ionomycin. Activation of cells by PMA and ionomycin leads to an increase in cell surface expression of certain markers such as CD69 and CD154, which can be detected using this cocktail.

-
Cell Activation Protocol:
1. Resuspend cells of interest in desired cell culture medium. Recommended cell suspension is between 1-2 x 106 cells/mL, although effective activation can be obtained with higher or lower concentration.
2. Completely thaw vials in 37°C water bath.
3. Add 2 µL of the cocktail to each mL of cell suspension.
4. Incubate cells at 37°C in a CO2 incubator for 6 hours or the time period of interest.
5. Harvest activated cells and centrifuge at 350g for 5 minutes. Discard supernatant.
6. Add 2.5 mL of Cell Staining Buffer (Cat. No. 420201) to the cell pellet, mix by vortex or pipetting, then centrifuge at 350g for 5 minutes. Discard supernatant.
7. Repeat step 6.
8. Cells are now ready to be tested for surface markers or proteins of interest.
Note: If investigators are interested in detecting intracellular proteins following activation, this product can be used in conjunction with Monensin (Cat. No. 420701) or Brefeldin A (Cat. No. 420601).
This product is temperature sensitive; repeated freeze/thaw is not recommended.
Intracellular and surface flow staining, as well as ELISA, can be performed following activation of cells with this cocktail. - Additional Product Notes
