STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Tumor Necrosis factor Receptor SuperFamily Member 6 (TNFRSF6), also known as FAS receptor (FasR), apoptosis antigen 1 (APO-1 or APT) or CD95, is a death receptor on the surface of cells that leads to apoptosis. It is one of two apoptosis pathways, the other being the mitochondrial pathway. FasR is located on chromosome 10 in humans and 19 in mice. FasR forms the death-inducing signaling complex upon ligand binding. Membrane-anchored FasR ligand trimer on the surface of an adjacent cell causes oligomerization of Fas. Some reports have suggested that the extrinsic Fas pathway is sufficient to induce complete apoptosis in certain cell types through DISC assembly and subsequent caspase-8 activation. These cells are dubbed Type 1 cells and are characterized by the inability of anti-apoptotic members of the Bcl-2 family (namely Bcl-2 and Bcl-xL) to protect from Fas-mediated apoptosis. Diseases associated with FAS include autoimmune lymphoproliferative syndrome and fas-related autoimmune lymphoproliferative syndrome.
