General Procedure
- Place gel cartridge in gel box with loading buffer
- Load samples
- Run the gel
- Place gel in DI water for one hour
- Remove water, add staining agent (GelCode Blue), leave on rocker overnight
- Remove GelCode Blue, add DI water. Refresh DI water every hour until gel bands are visible
SDS PAGE Gel Buffer Information
4X Loading Buffer
