Protocol

· Transfer the proteins @ 50volts (400mAmps) for 1 hours in cold room.

· After transfer briefly rinse the blot once in ddH2O and once in TBST.

· Block in 5% Non Fat dry milk (NFDM) in TBST at least for an hour @RT on a shaker.

· Incubate in the primary antibody diluted in TBST with 2.5% NFDM @RT for 2 hours or @ 4oC O/N on a shaker.

· Wash three times 5min each in TBST on a shaker.

· Incubate in the secondary antibody diluted in TBST with 2.5% NFDM @RT for 1hour on a shaker.

· Wash three times 10 min each in TBST on a shaker.

· Add 3 m l of Hydrogen Peroxide to 10ml of ECL mix and incubate the antibody probed blot for at least one minute.

· Wrap the blot in a Saran Wrap, squeeze out the excess reagent with a kim-wipe and expose it to film.
