Preparing 1x Running Buffer

Denaturing Samples: Add 50 ml 20x NuPAGE Tris-Acetate SDS Running Buffer to 950 ml dH2O.

Native Samples: Add 100 ml 10x Tris-Glycine Native Running Buffer to 900 ml dH2O.

 

 

Load Samples

Load the appropriate concentration of your protein sample on the gel.

 

 

Load Buffer

Fill Upper (200 ml) and Lower (600 ml) Buffer Chambers with the appropriate 1x Running Buffer.

For Reduced Samples: Use 200 ml 1x Running Buffer with 500 ml NuPAGE Antioxidant in the Upper Buffer Chamber.

 

 

Run Conditions

Voltage:           150 V constant

Run Time:       1 hour (denaturing gel), 2-3 hours (native gel)

Expected:        40-55 mA/gel (start); 25-40 mA/gel (end) for denaturing gel

                        18mA/gel (start); 7mA/gel (end) for native gel

 

 

 

 

Gel

 (Hand-written annotations found on original copy).

  1. Make 600 ml running buffer (H2O in bottle, 30 ml 20x, H2O to 600 ml mark).
  2. Take out gel, remove comb and tape on bottom.
  3. Put into chamber, put in 2 gel, clamp closed w/ white block/clamp device.
  4. Fill upper chamber, add 0.5 ml antioxidant.
  5. Rinse wells.
  6. Load 7 markers, well holds ~35?

*Adr1 extracts ~10-20 ml.

7. Up to 150 V, ~ 1hr.
