How can I concentrate my protein extract which would give me the best final yield?
My question arises from the feint Western blotting band which indicated low protein expression. I've already loaded 30-40ug protein. Should I load more? concentrate my stocks?

I have had the same problem with a very low expressed group of proteins. I use a large gel that I have to make since no one sells them and make a large well, then I add 100 ug of protein and use an biotination secondary antibody and a senstive ECL kit like Pierce's West pico.
