Objectives

  1. Run electrophoresis(SDS-PAGE) of pepsin and pepstatin samples prepared on 2013/09/24
  2. Finish running UV-Vis samples of pepsin and pepstatin samples prepared on 2013/09/24


Electrophoresis

  • Electrophoresis was run on a Bio-Rad mini protean system with pre-cast TGX gels.
  • Used Coomassive blue staining for the development


General Protocol:

  1. Prepare the gel and assemble the electrophoresis cell
    • Refer here for exact details on how to assemble the unit.
    • Remove comb and tape from the gel
    • Rinse the walls with running buffer (30.0 Tris, 44.1g glycine, 10g SDS, H2O to 1L)
    • Assemble cell
    • Fill the inner and outer buffer chambers with running buffer
  2. Load samples prepared yesterday
    • Note: Also loaded two hemeglobin samples for comparison and pepsin and pepstatin reactions left overnight(these were prepared in the same fashion as 2013/09/24. In total ran 12 samples.
    • Note: Loaded entire 20μL samples
  3. Run electrophoresis for 30 minutes at 200V
  4. Develop stain of the gel
    • Place gel in fixant solution (40% methanol, 10% acetic acid, 50% water) for 30 minutes
