[Histonet] Re:Mucin containing cells too blue

[DNon]

I had this very same issue with Surgipath Hematoxylin a few months ago. 
Jumped through hoops to try to fix the problem.  Found a very effective and 
fast solution after getting excellent responses on Histonet:  I changed 
brands of hematoxylin.  Kept Surgipath reagents for the rest of our H&E 
staining, but switched to a rebranded Hematoxylin from a local source ( 
Belair Instruments in New Jersey...dont know who the actual manufacturer of 
the Hematoxylin is, but it works great).  It seems more than a few other 
people have had the exact same issue with Surgipath hematoxlyin.  Alot of 
people had switched to various different brands and fixed the problem.  Its 
a shame as we used the Surgipath brand hematoxylin for 12 years without 
issue until this happened.
