[Histonet] Help with a brown and brenn, Brown and Hopps question

[dennis applegate]

Hello everyone,
I am a student of histology at clover park technical college and we have a
task to complete.  We have to find out who the Brown of the Brown and Brenn,
Brown and Hopps stain is.
If anyone can point me into the right direction I would greatly appreciate
it.  I have found no info on the internet thus far.

Thanks

DA
