what's a quick way to exclude molecules > 1kD from cell extract?

   I need a simple way to size-exclude molecules greater than 1 kD from a
cell extract. Is there some column or centrifuge filter I can buy such
that I can just load my stuff on top and get everything smaller than 1 kD
out the bottom? Preferably without taking too much of a dilution or loss.
If anyone has any info, please email to mlevin at fas.harvard.edu. Thanks
very much!
