we are using the CLARITY technique to clear Rat brains and we would like to label astrocytes and neurons in the cerebral cortex and to be able to count them. We tried to stain it using NeuN and GFAP, but it didn’t stain. Do you have any recommendations/thoughts on why it did not work, or any specific steps we should follow? we followed steps on
If you still need help on this subject it would be helpful to provide more information, such as the following:
How thick is your tissue? How long have you cleared it? Did you use PACT (A4P0)? What were your staining conditions (antibody, concentrations, time, temperature)?
What is your imaging setup?
Otherwise, I recommend the article below, where the authors stained and counted PV-neurons in the cortex. They provide several suggestions to improve staining efficiency in thick CLARITY tissue.
Immunocytochemistry remains a valuable and necessary tool for biologists working with nematodes, even those nematode model organisms with advanced molecular genetic tools and transgenics. Because of the highly idiosyncratic nature of successful immunostaining procedures, innovations can still be found for this long-established technique. Heat-induc...
