first you have to remove traces of fixative (acetic acid is a somewhat reversible fixative). soak the gel in water.
then, use sds (up to 0.05%) in the transfer buffer to help resolubilize the protein.
it may still be inefficient but you should get some transferred.
a bigger concern will be the stain and how it effects post-transfer processing (some of the stain will be removed from the protein and should pass through the membrane).
