ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 1L15 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Caspase-8. It targets an epitope within the p18 subunit

Immunogen

KLH-conjugated linear peptide corresponding to 15 amino acids from the p18 subunit of human Caspase-8.

Application

Quality Control Testing

Evaluated by Western Blotting in HeLa cell lysate.

Western Blotting Analysis: A 1:10,000 dilution of this antibody detected Caspase-8 in HeLa cell lysate.

Tested applications

Western Blotting Analysis: A 1:10,000 dilution from a representative lot detected Caspase-8 in lysate from Jurkat cells treated with Staurosporin.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Caspase-8 in HUVEC and A431 cells.

Affinity Binding Assay: A representative lot of this antibody bound Caspase-8 with a KD of 1 x 10-12 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected Caspase-8 in human colon and kidney tissue sections.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-Caspase-8, clone 1L15 ZooMAb®, Cat. No. ZRB1426, is a recombinant Rabbit monoclonal antibody that detects Caspase-8 and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Target description

Caspase-8 (UniProt: Q14790; also known as EC:3.4.22.61, CASP-8, Apoptotic cysteine protease, Apoptotic protease Mch-5, CAP4, FADD-homologous ICE/ced-3-like protease, FADD-like ICE, FLICE, ICE-like apoptotic protease 5, MORT1-associated ced-3 homolog, MACH) is encoded by the CASP8 (also known as MCH5) gene (Gene ID: 841) in human. Caspase-8 is a cysteine protease that plays a major role in the extrinsic apoptotic signaling pathway via death receptors. In its inactive form, it associates with FADD by interactions between their DED motifs and within the FAS-FADD-Caspase 8 complex caspase 8 undergoes self-cleavage to convert to the active form. Activated caspase 8 is subsequently released to the cytosol and it cleaves downstream effector caspases 3, 4, 6, 7, 9 and 10. Highest expression of caspase-8 is found in peripheral blood leukocytes, spleen, thymus, and liver and it is barely detectable in brain, testis, and skeletal muscle. Caspase-8 is produced with two propeptides (aa 1-216 and 375-384) that are cleaved under appropriate signals to produce a p18 (aa 217-374) and a p10 (aa 385-479) subunit. Active caspase 8 is a heterotetramer that consists of two p18 and two p10 subunits. In human, nine different isoforms of caspase-8 have been described that are produced by alternative splicing. Isoforms 5, 6, 7, and 8 lack the e catalytic site and may interfere with the pro-apoptotic activity of the complex. 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, 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.
