[Histonet] Decreased Staining on Controls

[Annette Hall]

Hi,

We are having problems with are CD15 and CD30 antibodies using the
DakoCytomation Artisan. The controls seem lighter than when we first started
with this instrument 4 years ago. Our instruction has been to use "fresh"
controls. We cut controls and store them at 4 deg C for a few months. In
your experience, what do you consider fresh? How long do you keep cut slides
controls before you toss them?

Thanks,
