Recombinant humaan Galectine-3/LGALS3-eiwit

Galectin-3 is a member of the family of animal lectins, which selectively binds beta-galactoside residues. This protein is secreted from cells by ectocytosis, which is independent of the classical secretory pathway through the endoplasmic reticulum/Golgi network. Galectin-3 has been associated with the inhibition of apoptosis and the progression of cancer. It is normally distributed in epithelia of many organs, in various inflammatory cells, including macrophages, as well as dendritic cells and Kupffer cells. The expression of this lectin is up-regulated during inflammation, cell proliferation, cell differentiation and through trans-activation by viral proteins. Recombinant Galectin-3 protein was expressed in E. coli and purified by using conventional chromatography techniques.

The ED50 for this effect is less or equal to 15 µg/mL. Measured by its ability to agglutinate human red blood cells.
