Good morning! I believe that Cell Signalling is quite good in antibodies and perhaps you should have a look on their catalogue. Everything i bought from them seems to work quite well.

Best wishes,

Hi,

Just check Origene. http://www.origene.com/antibody/ they give a positive control with their Ab.

Y CST, alpha diagnostics, or especially endogenous controls from BD biosciences or calbiochem works well.
