[Histonet] CD15


Hi Histonetters,
We have recently had problems where our CD15 is NOT staining in any of
the Hodgkins cases we had - although, the CD30 is staining quite well. 
Our control will stain well but we have had 3 patients who have stained
negative with our procedure and yet positive at another institution.
This has been on both bone marrow cores and nodes.
We currently use Ventana's pre-dilute (clone MMA) on our Benchmark.
Has this happened to anyone else - or do you have any suggestions?
Thanks in advance.
