Osenses Protocols: Western Blot

.................................................................................................................................................................................

1. Run the SDS-PAGE at 250V.

2. Soak the gel for 10 min in transfer buffer then rinse it with Di water.

3. Soak the membrane for 5 min in Di water.

4. Semi-dry transfer at 10 V.

5. After transfer, rinse once the membrane with PBS and then wash 3x, 5 min each with PBS in 100 ml. Shake at 50 RPM.

6. Block with 1xPBS containing 1% LFDM for 30 min at RT with shake at 50 RPM.

7. Rinse with 70 ml of PBS.

8. Assemble the MPX (from LiCore) and add the primary antibodies (155 µl/channel). Incubate O/N in the fridge (3-5C).

9. Aspirate the antibodies and disassemble the MPX. Wash the membrane 5 times (5 min each) with PBST containing 0.1% Tween-20. Wash in 100 ml with shake 50 RPM.

10. Add the Sigma HRP-Goat anti rabbit diluted 1: 15,000). Add 6 ml per membrane (6x8 cm). Incubate 30 min to 1 hour at RT with 50 RPM shake.

11. Wash 4 times (5min each) with shake 50 RPM with 100 ml of  PBST.

12. Wash 6 times more with 100 ml of PBS with shake 50 RPM.

13. Prepare the ECL substrate from BioRad.

14. Pipette the substrate on the glass of the C-Digit. Place the membrane face down on the substrate, avoid air bubbles. Cover the membrane with Gladwrap and incubate 2 minutes. Then roll over the membrane. Scan the blot on C-Digit at High resolution (12 minutes).
