Dear Histologists,
Has anyone done TUNEL on 40 um flash-frozen rat brain sections? I have tried tweaking the protocol (we use the Millipore Apoptag kit  - S7101) from our ongoing 20 um slices by increasing the incubation times from 1 hour to 2 and 4 hours but we still get poor staining. Also, could I do overnight incubations? the tissue is flash frozen, but it does get fixed at the beginning of the protocol with PFA (4%) and subsequently with acetic acid-EtOH.
