Concentrating Small Protein

[Randall Willis]

Mike,

Another method to concentrate your protein would be to place it in a 
dialysis bag of ~1kD cutoff and place this into dry PEG.  This will 
serve to draw out the buffer solution while keeping back your protein.

Good luck...Randall C Willis, Publisher, Aliquotes Press
