Thanks for your feedback. Just a quick one. I've read about 'macrophage lysis buffer' which requires much more recipe such as Tris buffer, NaCl, glycerol, EDTA, PMSF and protease inhibitor (Neil E. Reiner (2009). Macrophages and Dendritic Cells. Methods and Protocol. Springer Protocols). What's your opinion?
I am agreed with Asmita, 1% of Triton is good enough. It all depends what you want to do with lysate afterwards. If you want measure enzyme activity, then you don't add the protease inhibitors cortail in the buffer.
