I want to dry down a large quantity of liposomes and aliquot and freeze. I want to be able to play around with the inside conditions, changing buffers, dyes, etc. I can make a 2X buffer to hydrate the lipids with and then add 2X of dyes and salts that I want to test. What if I want to change the buffer though? Centrifuge at what speed to pellet lipids, wash the lipids with new buffer, freeze-thaw to encapsulate new buffer condition? Any tips? Thanks!
