The following protocol used formalin-fixed paraffin-embedded human tonsil tissue.

  1. Deparaffinize and rehydrate the tissue section. 
  2. Perform heat-induced antigen retrieval with 1mM EDTA pH 8.0 at 123˚C for 3 minutes in a pressure chamber. Wash the slide twice for three minutes each (50mM Tris-HCl pH 8.0, 150mM NaCl in distilled water).
  3. Incubate the tissue section with 1% BSA/PBS block. 
  4. Incubate the tissue section overnight at 4˚C with Mouse Anti-Human Eotaxin-2 at 10.0 μg/mL. Wash the slide twice for three minutes each.
  5. Incubate the tissue section with an HRP polymer kit according to the manufacturer’s protocol. Wash the slide twice for three minutes each.
  6. Incubate the tissue section with the DAB chromogen.
  7. Counterstain the tissue section with hematoxylin.
  8. Coverslip the sections with mounting medium.
