In the past, I have used agarose gels to separate and analyze (by
coomassie) a very large protein subunit (500,000 M.Wt.) under native
conditions. I wonder why that method couldn't be scaled up. The
company FMC has several grades of agrose and I found one of them
suitable for protein work (Diclaimer: I am in no way associated with
that company). Give it a shot.
