Purity ~98% (SDS-PAGE, HPLC). Galectin-7 belongs to growing family of evolutionary conserved animal lectins. Galectins consists of beta-galactoside binding lectins that contain homologous carbohydrate recognition domains (CRDs). Galectin has the ability to induce apoptosis of activated T-cells and T-leukemia cell lines. Other activities include cell differentiation and inhibition activity of CD45 protein phosphatase activity. Galectin also binds beta-galactoside as well as CD45, CD3 and CD4. Source: Recombinant protein corresponding to 136aa residues from human Galectin-7, expressed in E. coli. Molecular Weight: ~15.4kD Biological Activity: Measured by its ability to agglutinate human red blood cells. The ED50 for the effect is typically 1-7ug/ml. Endotoxin: <0.1ng/ug
