Hi,
I want to evaluate neuronal activity after 15 minutes in my slides using immunofluorescence. I can't use c-fos because mRNA levels peak after 15 min, but protein levels seem to be increased after an hour. I'll try to use P-p44/42 MAPK (Erk1/2) (Thr202/Tyr204). Can somebody experienced with using this staining share their experience. How specific is it compared to c-fos for use in evaluation of neuronal activity?
