I've been doing this stain for years and the protocol that I use came from John Kiernan (Histonet Archives). If you use Sirius Red F3B (CI 35782) the stain will be good for up to 3 years. Don't use a dye that does not have this CI #.
I have used the stain over and over and it always produces excellent results. I stain for one hour in the PSR, wash in two quick changes of Acidified Water. I usually do not do the hematoxylin step because the researchers requesting the stain prefer it that way. The tissue I stain most often with PSR is carotid and/or aorta and heart but I have done a beautiful stain on the back of the eye including optic nerve. With polarized light it is a thing of beauty to observe.
