See Also: Equipment List

  1. Prepare all necessary solutions.

  2. Cut nitrocellulose transfer membrane and 6 sheets of GB004 gel blot paper to the EXACT size of the polyacrylamide gel.

  3. Equilibrate gel in cathode transfer buffer for EXACTLY 5 minutes.

  4. Prewet the nitrocellulose transfer membrane in anode transfer buffer for 5 minutes.

  5. Wipe the surface of the anode (in the base of the blotter) with a paper towel that has been saturated with anode buffer.

  6. Prewet 3 sheets of GB004 gel blot paper until saturatedwith anode buffer and place them on the anode.

  7. Place nitrocellulose transfer membrane (prewet) on top of the saturated stack of gel blot paper.

  8. Remove all air bubbles by gently rolling a glass pipet or stirring rod over the stack (EXTREMELY IMPORTANT!!!)

  9. Place the equilibrated prewet gel in the transfer membrane, taking care not to create air bubbles. (EXTREMELY IMPORTANT!!!)

  10. Saturate 3 sheets of GB004 gel blot paper in cathode buffer and place them on top of the gel, removing air bubbles completely.

  11. Wipe the surface of the cathode (in the top) with a paper towel saturated with cathode buffer.

  12. Place the lid (cathode) on the base (anode) lining up the red and black rods with the holes in the lid.

  13. Connect the black cable on the Pronto lid to the hole containing the (-) electrode.

  14. Connect one end of the red cable to the hole containing the (+) electrode on the lid

  15. Connect both the red and black cables to the power supply [black = (-) and red = (+)].

  16. Plug in and turn on the power supply
