分子别名(Synonym)

TNFSF18,AITRL,TL6,hGITRL,GITR Ligand

表达区间及表达系统(Source)

Human GITR Ligand, His Tag (GIL-H5249) is expressed from human 293 cells (HEK293). It contains AA Gln 50 - Ser 177 (Accession # AAH69319.1).

Predicted N-terminus: His

蛋白结构(Molecular Characterization)

Online(Gln 50 - Ser 177) AAH69319.1

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 20.5 kDa. The protein migrates as 23 kDa and 26 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Protocol

背景(Background)

Tumor necrosis factor ligand superfamily member 18 (TNFSF18) is also known as Glucocorticoid - induced TNF-related ligand (GITRL or GITR Ligand), Activation - inducible TNF - related ligand (AITRL), which belongs to the tumor necrosis factor family. TNFSF18 is expressed at high levels in the small intestine, ovary, testis, kidney and endothelial cells. TNFSF18 / GITRL is up-regulated after stimulation by bacterial lipopolysaccharides (LPS). TNFSF18 Can function as costimulator and lower the threshold for T-cell activation and T-cell proliferation. TNFSF18 / GITR Ligand is important for interactions between activated T-lymphocytes and endothelial cells. TNFSF18 also mediates activation of NF-kappa-B.
