Newcomer Supply Newly Blue Stain Set provides a synthetic nuclear stain (hematoxylin substitute), that is indistinguishable from standard hematoxylin staining results.  Newly Blue nuclear staining is crisp with well delineated purple to blue nuclei and displays a clear contrast to cytoplasmic stains for precise cellular interpretation.



Fixation:  Formalin 10%, Phosphate Buffered (Part 1090)
Technique:  Paraffin sections cut at 4 microns
Solutions:  All solutions are manufactured by Newcomer Supply, Inc.

All Newcomer Supply Staining Sets are designed to be used with Coplin jar filled to 40 ml following the provided staining procedure.
