  1. Periodically remove the control, rinse in warm distilled water, check microscopically for adequate silver impregnation. Basement membranes should be dark brown.  If the tissue structures are not sufficiently dark, place slides back in heated silver solution.  Recheck at 2-3 minute intervals until desired intensity is achieved.
    1. Staining at room temperature will require longer incubation times.
  2. Microwave Modification:  See Procedure Note #7.
    1. Place sides in a plastic Coplin jar containing prepared Silver-Methenamine Working Solution (Step #3) and microwave at 70°C for 3 minutes.

PROCEDURE NOTES:

  1. Acid clean all glassware/plasticware (Part 12086) and rinse thoroughly in several changes of distilled water.
  2. Plastic (Part 5500), plastic-tipped or paraffin coated metal forceps must be used with silver solutions to prevent precipitation of silver salts.  No metals of any kind should come in contact with silver solutions. Only glass thermometers should be used.
  3. Preheating Silver-Methenamine Working Solution to 45°C-60°C prior to incubation is suggested for timely silver development. A water bath or oven can be used for preheating. Begin preheating the silver solution approximately 20-30 minutes before use.
  4. Staining at higher temperatures will cause the development reaction to happen faster, but may cause precipitate to form in the working silver solution and deposit on slides.  Maintaining the silver solution between 45°C-60°C will help to minimize precipitate.
  5. Drain slides after each step to prevent solution carry over.
  6. Do not allow sections to dry out at any point during procedure
  7. The suggested microwave procedure has been tested at Newcomer Supply.  This procedure is a guideline and techniques should be developed for use in your laboratory.
  8. If using a xylene substitute, closely follow the manufacturer’s recommendations for deparaffinization and clearing steps.

Saccomanno Collection Fluid Part 1361B
 
60 ml vial, 30 ml fill (50/cs)
Saccomanno Collection Fluid Vial Part 1361D

 

For storage requirements and expiration date refer to individual bottle labels.

 

APPLICATION:

Newcomer Supply Saccomanno Collection Fluid is a ready-to-use cytology pre-fixative and sample preservative, and fluid of choice for collection of sputum specimens.  Saccomanno Collection Fluid also provides a variety of applications for collection and transport of cytology specimens, such as:

    • Fine need aspirates (FNA)
    • Urine samples
    • Urinary tract washings
    • Bronchial washings and brushings
    • Bronchoalveolar lavage (BAL)
    • Gastrointestinal specimens

Saccomanno Collection Fluid works to partially fix and stabilize cytology specimens, protecting cells from decomposition and autolysis when specimen transport is required or when cytopreparation is delayed.  Mucoproteins will remain suspended in the collection fluid and cells can be reclaimed with centrifugation.

 

METHOD:       

Fixation: Add equal volume of Saccomanno Collection Fluid to cytology specimen.

      • For brushes, add enough collection fluid to fully cover.

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

 

FIXATION PROCEDURE: 

    1. After cytology specimen is collected and received in the laboratory, add equal volume of Saccomanno Collection Fluid to specimen that will be transported or held for an extended amount of time prior to cytopreparation.
        1. See Procedure Note #1.
    2. Store and/or transport specimen according to suggested temperature specifications for specimen type.
    3. Proceed with cytology sample fixation and processing method for specific specimen type.
        1. See Procedure Note #2.

 

PROCEDURE NOTES:

    1. Refer to laboratory guidelines for length of time a specific cytology specimen type can be held fresh prior to processing or addition of Saccomanno Collection Fluid.
    2. Saccomanno Collection Fluid is considered a cytology pre-fixative and not a substitute for final specimen fixation in appropriate strength alcohol.

PROCEDURE NOTES:

    1. Timings provided are suggested ranges. Optimal times will depend upon staining intensity preference.
    2. Smears containing primarily normal cell populations require minimum staining time; immature cells and bone marrow smears/films may require longer staining time.
    3. The color range of stained cells may vary depending on buffer pH and pH of rinse water.
        1. Alkalinity is indicated by red blood cells being blue-grey and white blood cells only blue.
        2. Acidity is indicated by red blood cells being bright red or pink and lack of proper staining in white blood cells.
        3. If necessary, adjust buffer pH accordingly to 6.8 +/ – 0.2.
