CD 28 may not be present in sufficient amounts on your sections (frozen
sections really should stain with almost all antibodies). Perhaps you need
to try an amplified detection method, ie, Vector Labs ELITE system or
equivalent (Streptavidin:hrp etc).
We carry several  CD28, CD80 and CD86 antibodies (including some
polyclonals which work with frozen sections).
You cna contact us and I can send you data on our antibodies if
Hope this is of help.
