The results for activation I have been observing have been scattered and inconsistent. I am looking for reagents or a protocol to reliably induce NLRP3 inflammasome activation and show a clear difference to the control. I am also concerned that the RAW 264.7 cells are reacting in an adverse manner to something I am overlooking. Any tips on how to keep RAW 264.7 cells from activating prematurely would be greatly appreciated.
