[Histonet] Alcoholic Eosin-Phloxine in tissue processing

[Diane Satterfield]

I am in the process of setting up a Leica TP1020 processor.  I was looking at someone else's SOP where in a 100% EtOH steps they add alcoholic eosin-phloxine.

Can someone explain to me what this does and do I have to add this to one of the 100% EtOH steps in the processing.

Thanks
Diane
