Buffer for lyophylization

[Mark Dalton]

Michael
I would use amonium acetate or am. carbonate at 50mM if you wish to 
totally get rid of the salt by mult. lyopholyzation steps. Just keep 
adding water and refreezing and relyopholyze the amonium acetate/carb 
will disipate after two or three cycles.
