gel with 1-10 micron pores

Dear netters:

	I am trying to separate 1-10 micron Nuclear Polyhedrosis Virus 
from microsporidia which is only slightly bigger, ca. 15 microns.

	I have tried ultra-centrifugation on a sucrose gradient without 

	I ran some stock NPV on 0.3% and 0.7% agarose gels for 
two hours today.  There appeared to be a little movement in the 0.3% 
gel.  But it could just be that the wells are bulging.  I'll know 
tomorrow when I continue the run.
	Meanwhile, I want to mix up some new gels to run along side the 
one's I already have.  There was an allusion to electrophoresis on a 
sucrose gradient in a 1970's text on plant viruses.  I'm tempted to mix 
some sugar into the TAE buffer I used to make the 0.3% agarose gel.  
Perhaps this will make it viscous enough so that I can further reduce the 
concentration of agar?
	Any suggestions?

PS.  I'm in Bangkok and don't have direct access to news groups.  Please
