Far as I know, one cannot stain paraffin embedded material with x-gal. We will do either whole mount X-gal staining, post-fix, and then paraffin process and section, or we will fix, sucrose cryoprotect, freeze and then cryosection to do the X-gal staining. Send me an email if you want to have our protocols for doing either.
