We have used Prefer for about 6 years now.  When we started using it, there
were some changes we had to go through with the help of our pathologists.
It takes patients and persistence to develop your IHC protocols.  There are
no antibodies that we can't get to work... we have a 100% success rate!  We
also use almost all BioGenex antibodies and reagents with the OptiMax
automated stainer.
