p-Akt help!

I'm working with NCI-H322 cell line and trying to detect p-Akt by Western blotting with Cell Signaling Ser-473 p-Akt primary Ab and anti-mouse secondary.

The problem is that my p-Akt band keeps showing up at the wrong molecular weight. I work with another cell line (A549) and the p-Akt band shows up at the correct place (60-kDa) but H322 keeps giving me about 150 kDa bands for p-Akt even though A549 shows up fine in the same run.

Anyone got any ideas?

Why don't you try Southern

Why don't you try Southern biotech's anti AKT antibody on NCI-H322 cell line . We have tried that antibody several times in different cell lines, it was constantly located on 57KD. You can call their customer service to get a free sample, the Catalog Number is 10946-01. the telephone number is 205-945-1774.

you might want to try the

you might want to try the same antibody from a different company. I think the phosphorylated protein should show the band where it is supposed to show., So, with a different antibody and with a positive control ( here A549) , you might want to repeat the experiment.
