Newcomer Supply Hematoxylin Stain Set, Weigert Iron is the preferred nuclear stain in conjunction with trichrome and mucin stains.  Iron hematoxylin is the optimal nuclear stain when succeeding stains are lengthy or acidic, where the use of an aluminum-mordanted hematoxylin stain would have a tendency to decolorize.



Fixation:  Formalin 10%, Phosphate Buffered (Part 1090)

Solutions:  All solutions are manufactured by Newcomer Supply, Inc.

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

Other tissue components Dependent on stain procedure or counterstain used



    1. Drain slides after each step to prevent solution carry over.
    2. Do not allow sections to dry out at any point during procedure.
    3. If Weigert Iron Hematoxylin is not completely washed from tissue sections, nuclear and cytoplasmic staining may be compromised.
    4. If using a xylene substitute, closely follow the manufacturer’s recommendations for deparaffinization and clearing steps.
