I've used Filtron devices with a 10k and 3k cutoff.  They usually work very
well, though at very low protein concentraions, I tend to lose alot of my
material.  This could be a specific probelm of my protein though.  If you need
to concentrate for poading on a gel, startagen makes a resin that specifically
binds proteins (sort of like glass milk for proteins) which works exceptionally

Good luck!

the enemies of life ... we are not ashamed, nor are we afraid, nor are we
anything but determined to fulfill the legacy for which my friend fell..."
