Description_x000D_ General description_x000D_ GITRL (Glucocorticoid-induced TNF receptor ligand) is expressed on dendritic cells (DC), monocytes, macrophages, B cells, activated T cells, endothelial cells, osteoclasts and various healthy non-lymphoid tissues (e.g. testis). GITRL is constitutively expressed and released as soluble form by solid tumors and various hematopoietic malignancies. GITRL causes differentiation of osteoclasts, activation of macrophages, but also alteration of carcinoma and leukemia cells and influences apoptosis. Binding to GITR is important in regulating T cell proliferation and TCR-mediated apoptosis. GITRL is implicated in development of autoimmune diseases and in the immune response against infectious pathogens and tumors._x000D_ Physical form_x000D_ Solution in 10 mM glycine, pH 10.0._x000D_ Other Notes_x000D_ The extracellular domain of mouse GITRL (aa 45-173) is fused at the N-terminus to a FLAG®-tag._x000D_ Legal Information_x000D_ FLAG is a registered trademark of Sigma-Aldrich Co.
