Cell Stimulation Reagent (Without Brefeldin A)
Cell Stimulation Reagent (without Brefeldin A) 500x is a mixture of Phorbol-12-myristate-13-acetate (PMA) and ionomycin. PMA activates protein kinase C and ionomycin acts as a Ca2+ ionophore allowing movement of Ca2+ across membranes. Activation of cells with PMA and ionomycin leads to an increase in surface expression of certain markers such as CD69 and CD154 and the production of cytokines such as IL-2, IFN-gamma and TNF-alpha.

- Instructions For Use
- 1. Resuspend 1 x106 - 2 x106 cells per ml in cell culture media
2. Thaw the Cell Stimulation Reagent (without Brefeldin A) 500x (BUF076A) in a 37oC water bath
3. To each ml of cell suspension add 2 μl of BUF076A and incubate cells in a CO2, 37oC incubator for 6 hours
4. Harvest cells and centrifuge at 300-400 g for 5 minutes. Discard supernatant
5. To wash the pellet, add 10-20 ml of Cell Staining Buffer (BUF073), vortex to resuspend the pellet then centrifuge at 300-400 g for 5 minutes. Discard supernatant and repeat step 5 for a second time
6. Stain for surface markers or proteins of interest and analyze cells using flow cytometry
Note: Aliquot product to avoid repeat freeze-thawing. Time and culture conditions may need to be optimized. To detect intracellular staining following activation, the Cell Activation Reagent (without Brefeldin A) 500x (BUF076A) can be used with Monensin Solution (BUF074) or Brefeldin A Solution 1000x (BUF075).
