RIPA buffer

	We don't use RIPA buffer here in our lab, but I have used it previously.
The reference for the buffer is in PNAS 87:9396,1990.
Here is my recipe:
20 mm Tris pH 7.4
50mm NaCl
50mm NaF
5mm EDTA
20mm Na pyrophosphate
1mm PMSF
1mm Na orthovanadate
1.0% TritonX-100

In my limited experience the Triton is optional in some usages when lysis
of cells is not needed. The reference should be clearer on this point.
Hope this helps.
