Giemsa stain
  • As a hematology stain, works best with alcohol fixed smears
  • As a histology stain, detects mast cells and microorganisms, such as Giardia or Helicobacter
  • A "Romanowsky-type" stain, composed of mixtures of methylene blue, azure, and eosin compounds
  • Methylene blue is a metachromatic stain, meaning that some tissue components (mast cell granules, cartilage, mucin, amyloid) stain purple and not blue

  • Rabbit Monoclonal Primary Antibody designed to qualitatively detect presence of Helicobacter pylori in formalin-fixed, paraffin-embedded gastric biopsy tissue via light microscopy
