  • Function

    Binds galactosides. Has high affinity for the Forssman pentasaccharide. May play a role in thymocyte-epithelial interactions relevant to the biology of the thymus. Inhibits cell proliferation. It is a ligand for HAVCR2/TIM3. Induces T-helper type 1 lymphocyte (Th1) death. Isoform Short acts as an eosinophil chemoattractant.
  • Tissue specificity

    Peripheral blood leukocytes and lymphatic tissues. Overexpressed in Hodgkin disease tissue.
  • Sequence similarities

    Contains 2 galectin domains.
  • Domain

    Contains two homologous but distinct carbohydrate-binding domains.
  • Cellular localization

    Cytoplasm. Secreted. May also be secreted by a non-classical secretory pathway.

  • IHC image of galectin 9/Gal-9 staining in Human normal Tonsil formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab153673, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
