    Product Information

    Product Usage Information

    This product is the carrier free version of product #8873. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

    This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

    BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

    Formulation

    Supplied in 1X PBS (10 mM Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

    For standard formulation of this product see product #8873

    Storage

    Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

    Specificity / Sensitivity

    Caspase-8 (F5K9P) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total caspase-8 protein, including the p10 subunit of the activated protein.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro394 of human caspase-8 protein.

    Background

    Apoptosis induced through the CD95 receptor (Fas/APO-1) and tumor necrosis factor receptor 1 (TNFR1) activates caspase-8 and leads to the release of the caspase-8 active fragments, p18 and p10 (1-3). Activated caspase-8 cleaves and activates downstream effector caspases such as caspase-1, -3, -6, and -7. Caspase-3 ultimately elicits the morphological hallmarks of apoptosis, including DNA fragmentation and cell shrinkage.

    In addition to functioning as a key initiator caspase for extrinsic apoptosis, more recent studies have identified caspase-8 as a regulator of inflammatory necrotic cell death pathways such as necroptosis and pyroptosis (4,5). Activation of caspase-8 leads to cleavage of RIPK1 and RIPK3 to inhibit necroptosis (6,7). As a result, caspase-8 deficiency in mice, which is embryonic lethal, can be rescued by deletion of the necroptosis proteins RIPK3 or MLKL (8-11). Additionally, in some circumstances, caspase-8 is recruited to the inflammasome to trigger pyroptosis (12,13). Studies have also found that expression of an enzymatically inactive form of caspase-8 (C362S) causes embryonic lethality by inducing necroptosis and pyroptosis (14).
