- I used to run really long gels in Dr. Yoder's lab a Cornell. Instead
- of using a gel dryer, we would open the two glass plates (with the gel
- sticking to the back plate-hopefully!), fix the gel on the plate in
- Mehtanol/Acetic acid, and then dry the gel right onto the plate in a 95'C
- oven. You can then put your X-ray film right on the plate, cover with
- another glass plate (so it doesn't move around) and expose for however
- long you need in a light tight box. If your are really intent on getting
- the top of the gel, just cut another piece of X-ray film and put it on top.
- After you are done with the gel, strip it off the glass by soaking overnight
- in 3M NaOH.
