Hello Netters,

I'm afraid I'm not much of a protein person but even I have to run the
occasional SDS-PAGE gel.  Most of the time this gives no problem but just
lately the lower molecular weight bands are very fuzzy.  I'm running 10 to
20% gels PAGE gels.  My hunch is this is a salt problem but why is it only
appearing now?  I'm using Sigma Trizma base,  is this O.K.?  Speaking of which
is there any difference between Trizma base and Tris?
