Principle

Mast cell particles contain heparin and histamine etc. These are sulfuric acid esters, are heterochromatic, so with the metachromatic dye toluidine blue staining, it can be appeared heterochromatic purplish-red.

Main components

Reagent compositionMain ingredient
1. Toluidine blue solutionToluidine blue
2. Glacial acetic acid solutionGlacial acetic acid

Sample requirement

  • The tissue should be fresh and quickly fixed, and its particles destroyed by the long-term storage of the tissue.

Test procedure

  • 1. The slices are routinely dewaxed to water and washed once with distilled water.
  • 2. Toluidine blue solution staining for 20~30 minutes, slightly water washed.
  • 3. Differentiation of glacial acetic acid solution, until cell nuclear and particle clearly (Control under a microscope), slightly water washed.
  • 4. Dry with cold air (Not through alcohol), transparent by xylene then sealed with neutral resin.

Precautions

  • 1. Mast cells staining require fresh tissue and quickly fixed.
  • 2. Due to ethanol easy mast cell particles restore the orthochromatic light blue, so after staining, the section with cold air dried, do not use ethanol dehydration.
  • 3. This reagent should be used by professionals and interpretation of the results. Read the instruction manual carefully before use, use it within the validity period, and do personal hygiene protection.
  • 4. Dispose of waste according to the requirements of the hospital or environmental protection department after use.
  • 5. The production date, production batch number and expiration date are shown in the outer packaging.
