Who to ask about this protocol
The recommended volume of solutions for mini-gels is 50 mL
- 1hr (or more) 50% EtOH, 12%HOAc, 0.5 mL/L Formaldehyde (37%)
- 2 x 20min 50% EtOH
- 20 sec ddH2O
- 1 min 0.2 g/L Na2S2O3•5H2O
- 3 x 20 sec ddH2O
- 20 min 2 g/L AgNO3, 750 µL/L Formaldehyde (37%)
- 2 x 20 sec ddH2O
Prepare developing solutions in advance!
- 30 g/L K2CO3, 500 µL/L Formaldehyde (37%), 4 mg/L Na2S2O3.5H2O (for 50 mL just use the smallest granule you can find)
- Shake gently until developed (typically less than a minute)
- 1 min 1% Glycine
- 1 min ddH2O
- 10 min 1% Glycine
- 30 min ddH2O
- NOTE:Many of the silver stain solutions are hazardous waste and cannot go down the sink. Please dispose of them properly.
This is an example of how it should look:
