Lyophilized from a 0.2 µm filtered solution of PBS, pH 7.4.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 36.7 kDa.
The protein migrates as 37 kDa under reducing condition (SDS-PAGE analysis).
Measured by its ability of the immobilized protein to support the adhesion of Jurkat cells. The ED₅₀ for this effect is <3 μg/mL.
<0.1 EU per 1 μg of the protein by the LAL method.
Galectin-9 (Gal-9) is a lectin family member and is one of the tandem repeat-type galectins containing two carbohydrate recognition domains (CRD) connected by a linker region in a single peptide chain. The CRD is responsible for β-galactoside binding, and several binding partners for galectin-9 have been identified, including CD44, FGL, Gcgr, GLUT- 2, IgE, IgM, PDI, and Tim-3. Galectin-9 is constitutively presented in the small intestine, liver, uterine epithelial cells, skin epidermis, and esophageal epithelium. Galectin-9 contributing to cell growth, differentiation, adhesion, communication, and death. Accumulated evidence indicates that Gal-9 blockade promotes T cell immunity against tumors, suggesting that galectin-9 is a promising target for immunotherapy.
