- 2 Superposed cathode applications
- Electrophoresis : 20 mn at 180 V .
4) STAINING
- Stock solution : dilute 1 vial of powder in one liter of methanol , mix for 3
to hours then filter .
- About 5 mn before the end of the migration , mix in a dish : 30 ml of stock
solution + ml of sodium hydroxyde 1n ; (this quantity is for one plate ) .
- At the end of Electrophoresis time , put the plate in the staining dish 15mn
(not more ) acetate side up .
- At the end of the staining time , gently rinse the plate under tap water .
- Then put the plate in a plastic bag with some drops of water , close it
avoiding air bubbles .
5) SCANNING
- Scan with your densitometer at 525 nm .
SPECIAL NOTE
- If you want to keep the plate : put it for 10 mn in a solution composed of 80
% glacerin + 20 % methanol , let it drain and and dry it between two blotters .
- Spray the cellulose acetate plate surface for 2-3 secondes and let it dry at
room temperature .
