I was wondering if anybody might have an idea with the following
problem we are experiencing: we want to stain for blood vessels in
sections of mouse brain. Our experimental tissues have been fixed
overnight in 4% paraformaldehyde and have been sitting in PBS since.
We have tried staining with antibodies against desmin, SMA, and
collagen but we get NO specific signal. We recently tried a non-fixed
mouse brain and got desmin to work immediately. The problem is that
we need to use the fixed brains because they are our experimental
model and it would take too long (2 years to be exact) to generate the
same samples. If anybody has come across such a problem before, or
has a specific protocol for vessels that works on PFA fixed brain, we
would appreciate the suggestions!
thanks in advance!
