Default GAPDH Not visible on western blot

Hi,

I am trying to detect GAPDH in prostate tissue and its not visible. Tried a variety of Ab concs and also different blockers but still no joy. I'm not sure if there are large amounts of GAPDH protein expressed in prostate tissue, does anyone know if there is and also what other loading controls are good to use? I'm going to try alpha tubulin but any other ideas would be good.
Thanks!

Have you been able to detect any other bands on Westerns using the same samples?
What are your antibody concentrations/dilutions and the substrate being used?

Assuming that prostate tissue has no detectable levels of GAPDH, maybe try actin?
