Description			Galectin-9 (Gal-9) is a member of animal lectins that have an affinity to beta-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. Source: Recombinant protein corresponding to aa1-148 from human Galectin9, fused to His-tag expressed in E. coli. Accession: O00182 Molecular Weight: ~18.5kD (168aa) Biological Activity: Measured by its ability to agglutinate human red blood cells, the ED50 for this effect is ~2.5ug/ml.
