My guess is that there are probably dozens of possible buffers.  I can recall
during my recent quest to find some pre- and hyb buffers that there were four
different systems, each one claiming to be "the standard Northern hybridization
buffer".  I got each of these out of a different review article on northerns.
Which, by the way, all had different parameters on how to run "THE standard

I'll see if I can dig up the refs, this is an interesting question....
