Slab IEF

Tue Mar 2 04:33:49 EST 1993

I am doing isoelectric focusing on denaturing (6M urea) slab gels.
I am looking at two proteins of pI 7 and 6, or so.  The upper
band (pI 7) is always blurry, not well focused.  A complex mixture of
proteins shows that all the bands are not well focused in the top 
1/3 or so of the gel.  Could this be due to heat?  What else?
