Anti-Mouse Galectin-9 In Vivo Antibody – Low Endotoxin (RG9-1) [ICH1186]

ichorbio’s Anti-Mouse Galectin-9 In Vivo Antibody – Low Endotoxin (RG9-1) [ICH1186] is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.

Galectin-9 is expressed by many cell types, including T cells, B cells, macrophages, dendritic cells, astrocytes, mast cells, eosinophils, fibroblasts, endothelial cells, and epithelial cells.

Galectin-9 (Gal-9), a member of the galectin family of mammalian lectins, binds β-galactoside. Gal-9 is expressed by many cell types, including endothelial cells, the epithelium of the gastrointestinal tract, T cells, B cells, macrophages, and mast cells. Gal-9 plays a significant role in innate and adaptive immunity and regulates excessive immunity by suppressing interleukin (IL)-17 producing effector T helper cells (Th)17 and Th1 as well as by augmenting Foxp3+ regulatory T cells (Treg). In addition, Gal-9 induces monocytic myeloid-derived suppressor cells (MDSCs), granulocytic MDSCs, and plasmacytoid dendritic cell-like macrophages. Gal-9 also suppresses B cell receptor signaling and is regulated by I-branching of N-glycans. Additionally, Gal-9 stimulates the maturation of dendritic cells.

Gal-9 is thought to function by binding to specific carbohydrate moieties in receptor molecules expressed on the surface of its target cells, including the T-cell immunoglobulin- and mucin-domain-containing molecule-3 (Tim-3). Gal-9 is predominantly located in the cytoplasm but can also be secreted. Gal-9 is expressed by a variety of tumor cells, plays a role in tumor immunity, and can suppress tumor metastasis by blocking adhesion to endothelium and extracellular matrices. CD45, which regulates antigen receptor signaling, is a major glycoprotein receptor for Gal-9 on naive B cells.
