I read this abstract yesterday and thought to myself "....great, someone discovered MudPIT..." and promptly forgot about it and got back to work.
This morning I reread it. Unfortunately, I don't have time to read the paper before I go out the door on this ridiculously early morning, but....they appear to be doing SCX in their nanospray emitter....
Considering the way that I learned to do SCX involved a buffer with 8M salts of some kind, they are either doing something very different -- or they are replacing their mass spec every couple of days.
If you'd like to delve into this mystery you can find it here!
it's a pH gradient using SCX column, rather then SCX gradient
