General description

Galectin-9 (Gal-9) is a member of animal lectins that have an affinity to β-galactosides and Forssman pentasaccharide. It is strongly overexpressed in Hodgkin′s disease tissue and it might participate in the interaction between the H&RS cells with their surrounding cells and might thus play a role in the pathogenesis of this disease and/or its consistently associated immunodeficiency. Recombinant Galectin-9 protein was expressed in E.coli and purified by using conventional chromatography techniques.

Physical form

0.5 mg/mL in 20 mM Tris-HCl buffer (pH 8.0) containing 1 mM NaCl and 20% glycerol.

Galectin-9, a member of the galectin family, can promote tumor growth through inducing apoptosis in anti-tumor immune cells via T cell immunoglobulin and mucin domain 3 (TIM-3). On the other hand, galectin-9 also induces tumor cell apoptosis in many malignancies
