Recombinant humaan Galectine-9/LGALS9-eiwit

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. Recombinant Galectin-9 protein was expressed in E. coli and purified by using conventional chromatography techniques.

The ED50 for this effect is equal or less than2.5 µg/mL. Measured by its ability to agglutinate human red blood cells.
