Fix the gel in about 10% acetic acid (other fixers probably just as good),
wash the gel by shaking in water for 30 minutes (you can even just leave it
under running tap water), shake in 20 gel volumes of 1 Molar Sodium Salicylate
for 1 hour, then dry directly. The reference for this is Chamberlain JP (1979)
Analytical Biochemistry 98, 132-135.
Gels containing salicylate tend to take extra time to dry. You might want to
have a layer of plastic wrap over the gel and leave it there during exposure
to prevent sticking to the film.
