Scientific Data

Detection of Human Galectin‑9 by Western Blot. Western blot shows conditioned media from HT-29 human colon adenocarcinoma cell line, human peripheral blood lymphocytes (PBL), and human dendritic cells untreated (-) or treated (+) with 10 µg/mL PHA for 6 days. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human Galectin-9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2045) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). Specific bands were detected for Galectin-9 at approximately 36 and 40 kDa. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Galectin‑9 in Human PBMCs. Galectin-9 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) treated with Calcium Ionomycin and PMA using Goat Anti-Human Galectin-9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2045) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Galectin‑9 in Human Colon. Galectin-9 was detected in immersion fixed paraffin-embedded sections of human colon using Goat Anti-Human Galectin-9 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2045) at 0.3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to epithelial cells.

Background: Galectin-9
Galectin-9 (also known as Ecalectin and UAT) is a 40 kDa beta -galactosidase binding lectin that belongs to a tandem repeat group of Galectins. Activated cells such as T cells, PMNs, astrocytes, fibroblasts and endothelial cells can express Galectin-9, but its release requires select MMPs. Human to mouse, there is 69% aa sequence identity for Galectin-9.
