Here is the cresy violet stain we use. I also have a protocol which calls for a
1% cresyl violet solution, and increased staining time to 20-30 minutes, then
differentiation in 95% alcohol until most of the stain is removed. The following
method works well for us so it is the one I use routinely. Hope this helps.
Cresy Violet for Nissl Staining
The identification of nuerons in tissue sections or the demonstration of the
loss of nissl substaince. This is useful in determining neuronal damage.
Neurons contain Nissl substance, which is primarily composed of rough
endoplasmic reticulum, with the amount, form and distributioin varying in
different types of neurons. Because of RNA content, Nissl substance is very
basophilic and will be sharply stained with basic aniline dyes.
A section of spinal cord is a good control.
Cresyl Violet..............5 gm
Distilled water...........100 cc.
ripen 24-48 hours. Filter.
1. Deparaffinize well and hydate to water.
2. Stain 3-5 minutes in Cresy Violet solution.
3. Rinse in 2 changes of distilled water.
4. Quick dip in acid alcohol. Put immediately into water to stop
5. Wash in running tap water.
6. Dip quickly in 95% alcohol, then absolute alcohol.
7. Xylene-several changes. Mount in permount.
