可是我的是核酸步驟同蛋白的銀染步驟相同嗎??謝謝.. 步驟不是完全一致的, 具體如下 1. Separate plates while keeping the gel attached to short glass. 2. Fix the gel: Place gel in tray, cover with cold fix/stop solution and agitate well for 20 minutes. Gel may be stored in fix/stop solution overnight. Save fix/stop solution and place back in freezer. 3. Wash the gel: Rinse the gel 3 times for 2-3 min. each in ddH2O using agitation. Lift gel from solution and allow to drain 10-20 seconds. 4. Stain the gel: Transfer the gel to staining solution and agitate well for 30 minutes. 5. Pour 1L of the developing solution into a tray. Transfer staining solution to beaker. Rinse tray and fill with ddH2O. 6. Rinse gel for 5-10 seconds ONLY. Transfer to developing solution. 7. Agitate in developing solution until bands begin to appear. Transfer gel to remaining chilled developing solution for 2-3 minutes. 8. Fix the gel: add 1L of Fix/stop solution directly to developing solution and agitate for 2-3 minutes 9. Rinse gel twice for two minutes each in ddH2O. 10. Dry gel on glass Fix/stop solution Staining solution 200ml of glacial acidic acid 2g (1 packet) of silver nitrate (AgNO3) 1,800ml ultrapure water 3ml (1 vial) of 37% Formaldehyde Freeze for approx. 3 hours 2L ultrapure water Developing solution 60g (1 packet) Sodium Carbonate (Na2CO3) 2L ultrapure water **chill to 10oC.
