[Histonet] Brain and spinal cord

[Yahoo]

Hi All! 
I’m looking for some suggestions please on fixation for brain tissue and spinal cord submissions from necropsies. We are currently using 10% NBF and ask our pathologists to leave the samples overnight (but that doesn’t always happen!!). Does anyone use alcohol-based fixatives? And if so, how long? Does it affect IHC or any other staining? Do you still process with other routine biopsies (14 hour program)?
Thanks!
