• Target description: Tumor necrosis factor receptor superfamily member 6 (UniProt: P25445; also known as Apo-1 antigen, Apoptosis-mediating surface antigen FAS, FASLG receptor, CD95) is encoded by the FAS (also known as APT1, FAS1, TNFRSF6) gene (Gene ID: 355) in human. The interaction of Fas with its ligand FasL (FasL/CD95L) regulates numerous physiological and pathological processes that are mediated through extrinsic apoptotic cell death. It is critical for the maintenance of immune tolerance. Seven isoforms of Fas have been described that are produced by alternative splicing. Isoform 1 is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-25), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 26-173), a transmembrane domain (aa 174-190), and a cytoplasmic domain (aa 191-335). Isoforms 2 to 6 are secreted forms and isoform 7 is a dominant negative isoform that is resistant to Fas-mediated apoptosis. Isoforms 1 and 6 are expressed at equal levels in resting peripheral blood mononuclear cells; however, after activation there is an increase in isoform 1 and decrease in the levels of isoform 6. The binding of FasL to Fas drives Fas clustering and binding to FADD. Death domain of Fas that is localized in amino acids 230-314 is involved in its binding to FADD. FADD then recruits caspase-8 to form the death-inducing signaling complex (DISC) that is activated by specific post-translational modifications of the death receptor (DR), such as palmitoylation and O-linked glycosylation. The DISC mediates autocatalytic processing and activation of caspase-8, which propagate the death signal through proteolysis of effector other caspases such as caspases-3, 6, and 7. Mutations in FAS gene have been linked to autoimmune lymphoproliferative syndrome 1A that manifests in early childhood and results in the accumulation of autoreactive lymphocytes, which is characterized by non-malignant lymphadenopathy with hepatosplenomegaly, autoimmune hemolytic anemia, thrombocytopenia, and neutropenia. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity™, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
• Reconstitution: 300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
• Storage and Stability: Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
