Old school 2D gel electrophoresis

[Arne K Christensen]

I am interested in doing some proteomic work using 2D gel 
electrophoresis.  We have the hardware to run 2D gels, however our 
equipment is many decades old and uses tube gels to resolve in the first 
(IEF) dimension.  Most of the published in the last 10+ years describes 
a first dimension separation by immobilized pH strips, which is 
presumably better.

Does anyone in this group have experience using tube gels?  Does the 
newer method truly warrant the costs associated with it (BioRad cost for 
the power pack is ~$8,000)?

Does anyone have any advice to offer in using tube gels before I dive in?

Thanks,
Arne
