WebPlace dialysis tube and float assembly (cap-end down) in a beaker of the solution to be dialyzed against (e.g. water or 1% glycine for native IEF or sample buffer containing urea, reducing agent, and nonionic detergent for denaturing IEF; … WebOct 22, 2009 · against buffer A containing 50% glycerol for 24 h and stored at®20 °C.))) ... Then transfer the dialysis tube into the second buffer, made up with 2 M urea and so forth. The best way to do this is to make up the buffer without urea as a 2x solution (50 mM Tris, 20% glycerol, etc). Then add an equal volume of 8M urea to make the first (4M) buffer.
