APPLICATION:
Newcomer Supply Hollande Fixative, a ready-to-use picric acid based fixative with an added copper acetate component, provides excellent morphology preservation, increased nuclear and sub-cellular detail while stabilizing red blood cell membranes. Hollande Fixative is recommended for gastrointestinal tract biopsies and endocrine tissue.
METHOD:
Fixation:
- Larger Biopsies: A minimum of 4 hours to a maximum of 24 hours. To facilitate grossing, the tissue can be placed in Hollande Fixative for an hour to firm tissue; then cleanly trim to smaller pieces.
- Small Biopsies: A minimum of 1 hour is recommended.
Solutions: All solutions are manufactured by Newcomer Supply, Inc.
FIXATION PROCEDURE:
- Place fresh tissue specimen in Hollande Fixative as soon as possible after surgical excision.
- See Procedure Notes #1 and #2.
- Hold tissue specimens in Hollande Fixative until ready to process or a maximum of 24 hours.
- See Procedure Note #3.
- Rinse Hollande fixed tissue thoroughly in running tap water for a minimum of 15 minutes, followed by a minimum of 15 minutes in 70% ethyl alcohol (Part 10844) prior to processing.
- See Procedure Note #4.
- Place on tissue processor starting in Formalin 10%, Phosphate Buffered (Part 1090) fixation step.
PROCEDURE NOTES:
- The acidic nature of Hollande Fixative is generally enough to sufficiently decalcify small bone without additional decalcification steps.
- Hollande Fixative may grossly stain tissue green. This reaction is normal.
- Extended storage of tissue in Hollande Fixative is not recommended. After a maximum fixation time of 24 hours wash tissue in running tap water for a minimum of 15 minutes, then a minimum of 15 minutes in 70% ethyl alcohol; transfer Hollande fixed wet tissue to Formalin 10%, Phosphate Buffered for long-term storage purposes.
- It is essential that Hollande fixed tissue is thoroughly washed prior to tissue processing or an insoluble blue phosphate precipitate will form upon exposure to Formalin 10%, Phosphate Buffered.
- Dispose of Hollande Fixative as hazardous waste and/or according to local and state environmental regulations.
