I believe Andrea was asking about LOADING controls, not POSITIVE
controls. Suitable loading controls are legion, and depend on the cell
line you're using. Beta-actin, GAPDH and tubulin all come to mind.
Warning: these are often expressed at very high levels. I would not
use antibodies against them on the same blot as you're using for your
CREB and p-CREB targets.
Hope this helps.
