I've being doing westerns using NEN's Renaissance reagent, very similar to
the Amersham ECL.  I've been rinsing the blot in tris-buffered saline
after incubation with the chemiluminescence reagent before exposure of the
film.  It seems to help with the background, IMHO.  I don't know how well
it will or will not work with PHAST gels, YMMV.
