A double cylinder gradient former was used with 12% poly acrylamide gel mix in the inner cylinder and a 3% polyacrylamide gel mix in the outer cylinder that was stirred using a magnetic bead on a magnetic stirrer. A pump was connected to the flow tube and the flow rate adjusted at 5-8 to cast a 12-3% gradient gel. A 5% stacking gel was used. After the protein samples were run on the gradient gel, it was stained in instant blue over night under shaking. 3% resolving gel (for 25 ml)Water = 15.68 ml 30% Acrylamide = 2.5 ml 1.5 mM Tris (pH 8.8) = 6.3 ml 10% SDS = 0.25 ml 10% APS = 0.25 ml TEMED = 0.02 ml
