The end of the stacking gel? - EZ-Run, PRIME gel, NEXT GEL, etc. (Jul/08/2010 )

Hi everyone! Today I came across a catalog that advertised a product called EZ-Run, a new polyacrylamide blend that eliminates the need for the stacking gel. I googled my a** off, but I couldn´t find info about it. Have any of you tried these new products? Does anyone know the composition or the scientific basis of their sieving properties? Thanks!

you can get the information at the thermo fisher website

it is a proprietary formulation of acrylamide/bisacrylamide with sds and buffer (the buffer is probably the proprietary part).
