How do I concentrate a low molecular weight protein (less than 5kDa)
from gel filtration fractions ie. dilute???, keeping in mind that
filtration devices and dialysis tubing concentrate above this size.
I have tried ammonium sulphate precipitation (up to 80%) with poor
results. It just doesn't want to precipitate!!!
