Exactly how much of each reagent did you use? The 30:4 usually means
30% total acrylamide (acrylamide + bisacrylamide) of which 4% of the
total is bisacrylamide. So you should be weighing out 28.8 g
acrylamide/100 ml and 1.2 g bisacrylamide/100 ml.
I know you can get this into solution. In fact, I use Schagger and von
Jagow's Tricine gels for which the stock solution is 49.5%T, 6%C :)
