When I used to do a lot of in vitro translations with retic. lysate, I
would load a couple of hundred micrograms of protein on a single lane
on a 1.5 mm gel. Of course, >90 % of it was globin, but the other bands
would resolve fine. Make sure you have enough SDS to bind all the
protein in the sample.
