Removal of SDS from protein

	Electroeluting a protein from a gel, with a buffer containing SDS
will give you a solution with protein and SDS.  You can freeze dry this 
in a small tube, and then rinse/wash it a few times with 90% ethanol.  This 
gets SDS, coomassie-blue, dithiothreitol, and even tris buffer I think, out
of your protein.  

	Of course its dead, denatured, and spread all over the walls of your
tube in a film.   But that's the way you want it if your'e doing vapor phase 
HCl hydrolysis for amino acid analysis (PicoTag).  

	Maybe this is useful for what you're doing.... Good Luck
