One trick for concentrating proteins from the dark ages is to freeze a
tube of the protein at -20C. After frozen solid, place the tube on
the lab bench and let thaw undisturbed. The bottom of the tube will
contain concentrated protein and the top of the tube will be water.
In between is a gradient. You decide how much to discard from the top
and the remaining solution is concentrated protein. I hope this
