Davidson Marking System Tissue Dyes

Original marking system for laboratory applications requiring orientation of tissue specimens!

  • The dyes provide orientation and precise marking of the perimeter of tissue specimens.
  • The dyes can be used on either fresh or fixed tissue and are also appropriate when preparing for a frozen section.
  • The dyes allow grouping of several small specimens in a single cassette by staining each with a different color.

     

  

Method of Use:

  1. Shake tissue dye well before and througout each use.
  2. Carefully blot tissue to remove excess moisture.
  3. Apply dye directly to desired portion to tissue using an applicator stick or brush.  Cotton tipped applicators or brushes are effective for larger areas, while a wooden stick can be used for more specific, detailed application.
  4. Do not apply excess dye as this will prolong drying time.
  5. Recap bottle promptly to prevent evaporation.
  6. Allow dye to dry completely (1-2 minutes).  Once dry, the dye is permanently bonded to the tissue.
  7. No mordant is necessary, but if desired, acetic acid is appropriate and effective.
  8. Once dry, the processing of the tissue can be performed.

Caution: Never use these dyes directly on living patients.  Only use on excised tissue as the dyes are permanent and not sterile.
