Description

General description

Fas (also known as Apo-1 and CD95) is a 40-50 kDa cell surface glycoprotein and a member of the TNF receptor family. Fas is an apotosis signalling molecule that forms the death inducing signalling complex (DISC) upon binding by the Fas ligand trimer on an adjacent cell. The Fas receptor also trimerizes, after which it is internalized and can then bind to the adaptor molecule FADD. FADD facilitates binding of caspase-8. which is activated to induce caspase-8 mediated apoptosis. Fas also plays a role in T cell mediated cytotoxicity and T cell development. Fas is found in the thymus, liver, heart, and ovary, where it is expressed on a minority of resting T and B cells and monocytes. The antagonistic ZB4 clone anti-Fas monoclonal has been used to block the apoptosis-inducing activity of the Anti-Fas CH-11 clone in multiple publications.

This product does not induce apoptosis in cell culture.

Specificity

This antibody does not recognize TNF and mouse Fas.

This antibody recognizes the human cell surface antigen Fas expressed in various human cells, including myeloid cells, T lympho-blastoid cells and diploid fibroblasts. It does not induce apoptosis in cell culture.

Immunogen

Recombinant human Fas.

Application

Anti-Fas Antibody (human, neutralizing), clone ZB4 detects level of Fas & has been published & validated for use in WB, FC, NEUT.

Flow Cytometry: A previous lot of this antibody used 5-20 μg/mL. Western Blot: A previous lot of this antibody used 5 μg/mL.

Quality

Evaluated by neutralization of apoptosis induced by anti-Fas (human, activating), clone CH11 (Catalog # 05-201) treatment of human Jurkat cells.

Neutralization: 10-500 ng/mL of this antibody was incubated for one hour with human Fas-transfected cells and inhibited the anti-Fas (human, activating), clone CH11 (Catalog # 05-201). Cell viability was assessed using a WST-1 assay
