Hematoxylin staining solutions

Use Epredia™ Modified Harris Hematoxylin, a regressive nuclear stain, for both histology and cytology.


  • Formulation contains no mercury
  • More stable than conventional Harris Hematoxylin



Epredia™ Modified Harris Hematoxylin is an acidified formulation that provides traditional nuclear staining results. Harris Hematoxylin procedures require acid alcohol differentiation. The nuclear chromatin and cytoplasm are over stained and the acid alcohol is used to destain the cytoplasm and also remove excess staining from the nuclear chromatin. Staining times are typically in the 5 minute range. Our Differentiating Solution can be used successfully with Modified Harris Hematoxylin. Our Epredia Modified Harris Hematoxylin is more stable than most commercial Harris Hematoxylins. It will not abundantly auto-oxidize at the same accelerated rate as other Harris Hematoxylins. The potency of the stain will slowly change, however the staining viability will remain for longer times. The product will crystallize when exposed to colder temperatures. Simply filter the crystals or put the contents of the bottle and crystals on a heated stir plate (35° C) and the crystals will go back into solution. DO NOT BOIL! It is highly recommended to filter Modified Harris Hematoxylin on a daily basis.
