We've had good luck with the protocol of Robertson et al. Anal. Biochem.
167: 290-294 (1987). IEF gels are very fragile (5% polyacrylamide) and
thus would be difficult (but possible) to immunoblot. We use GelBond PAG
support film (FMC Bioproducts) to provide stability to the gels, but you
cannot transfer the gel to blotting paper when it's attached to the film.
Someone used to make a porous support film that permitted transfer, but I
