[Histonet] Caspase-3-problem

[Alonso Martinez-Canabal]

       Hi everyone,
     
        I have been trying to obtain a nice caspase-3-cleaved
immunohistochemistry  or immunofluorescence with frozen or vibratome sliced
brains (particularly hippocampus). I have been using the cell signalling
antibody, without a lot of success. I tried antigen retrieval with heating,
and combined heating with proteinase K digestion, with not good results.
Could you suggest me something? 
 I also would like to know of any control tissue, I know that in normal
young mouse brain should be some positive cells in the dentate gyrus, but do
you kno any other structure that could be usable? Like skin, or liver, or
anything like that?
   Thank you very much for your valuable help
 Alonso

I wear contact lenses in the lab, but I also wear safety glasses all the
time.  I have been wearing lenses in histology for over thirty years and
have never had a problem.

And yes, Terry, when I cut onions while wearing contacts, my eyes do not
water.  I believe they do protect your eyes!!
