3. Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis a. After pouring the SDS polyacrylamide gel, you realize that instead of 2 ml, you used 4 ml of 30% acrylamide/bisacrylamide solution for the preparation of the separating gel (in both cases for 5 ml, total gel volume). How would this affect the separation of your proteins during SDS PAGE? Explain your answer! b. You have to remake the gel and are now making sure just to add...

Carl has just finished purifying a protein and analysis by gel filtration indicated that the molecular weight of the native (undenatured) protein was 130,000 dalton. His advisor wanted him to determine whether this protein had quaternary structure using gel electrophoresis. He wants to be able to describe the molecular weight of each of the subunits and the forces involved in linking these subunits together (disulfide linkages and/or electrostatic, hydrogen bonding and hydrophobic interactions). Carl first analyzed his pure protein sample...

To do electrophoresis, you will need to make a solution called TAE, which is a specific mixture of Tris base, acetic acid, and EDTA. Assuming no errors and no spills, you will need a minimum of 50 ml 1X TAE to make your agarose gel plus 1 liter of 1X TAE for gel running buffer. TAE is normally made as a 50X concentrated stock.
