C57BL/6 mouse frozen thymus section was fixed with 4% paraformaldehyde (PFA) for ten minutes at room temperature and blocked with 5% FBS for 30 minutes at room temperature. Then the section was stained with 10 µg/mL of anti-mouse Galectin-9 (clone 108A2) Alexa Fluor® 488 (green) and CD90.2 (clone 30-H12) Alexa Fluor® 647 (red) overnight at 4°C. The image was captured with a 10X objective.

Description

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.

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.
