[Histonet] B+ fixative

[Patti Loykasek]

Hi all. We have a new client that uses B+ fixative. I am totally unfamiliar
with this fixative. I'd appreciate any info on it. My main question concerns
IHC on this tissue. We've done a CD20 with our standard heat pretreatment &
standard titer, and gotten a negative result - even internal controls are
negative. I'd really appreciate some help with this. Thanks.
