Application Abreviews Notes
IHC-P Use a concentration of 4 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB 1/500 - 1/1000. Detects a band of approximately 40 kDa (predicted molecular weight: 40 kDa).
ELISA 1/5000.
ICC/IF 1/500 - 1/1000.


  • 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.

  • Ab69630 recognizes the partial tagged recombinant Human galectin 9/Gal-9 protein (galectin 1 domain only) which has an expected molecular weight of 19 kDa.

  • ab69360 (4µg/ml) staining galectin 9 / Gal-9 in human lymphoma using an automated system (DAKO Autostainer Plus). Using this protocol there is cytoplasmic and secreted staining throughout the tumour.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
