Galectin-9 is a mammalian lectin with a molecular weight of 40 kD that has two conserved carbohydrate recognition domains (CRDs) and forms homodimers. It recognizes N-acetyllactosamine (Galbeta1-4GlcNAc) and T-antigen (Galbeta1-3GalNAc); Tim-3 has been reported as its ligand. Galectin-9 is expressed by lymphocytes, dendritic cells, granulocytes, eosinophils, astrocytes, endothelial cells, fibroblasts and thymus epithelial cells. It may be retained intracellularly or be transported to the cell surface where it is cleaved, thereby generating a soluble form. Galectin-9 is involved in events such as cell aggregation, cell adhesion, chemotaxis and apoptosis. Importantly for the regulation of the immune response, Galectin-9 induces regulatory T cells and suppresses Th1 and Th17 responses.Product Details

- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. For Western blotting, the suggested use of this reagent is 0.5 - 2.0 µg per ml. For immunohistochemical staining on frozen tissue sections, the suggested use is 5-10 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
Clone 108A2 recognizes the linker peptide of mouse Galectin-9; it does not cross-react with stable Galectin-9 (which is biologically active, genetically engineered, linker-less Galectin-9)3. Additional reported applications (for the relevant formats) include: sandwich ELISA as capture antibody1 and immunohistochemical staining of paraffin2 embedded tissue sections.
