    Product Information

    Product Usage Information

    This product is the carrier free version of product #72337. 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 #72337

    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

    TNF-R2 (E8D7P) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total TNF-R2 protein. This antibody cross-reacts with an unidentified protein of 180 kDa in some cell extracts.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human TNF-R2 protein.

    Background

    TNF-α is an important cytokine produced by numerous cell types, including neutrophils, activated lymphocytes, macrophages, and NK cells. It plays a critical role in inflammatory responses and apoptosis (1). TNF-α exists as a membrane-anchored and soluble form, both of which show biological activity. Response to TNF-α is mediated through two receptors, TNF-R1, which is widely expressed, and TNF-R2, which is expressed mainly in immune and endothelial cells (2). Antagonists to TNF-α have been validated as therapeutic targets for rheumatoid arthritis and other immune disorders (3).
    The two receptors for TNF-α, TNF-R1 (55 kDa) and TNF-R2 (75 kDa), can mediate distinct cellular responses (4,5). In most cases, cytotoxicity elicited by TNF has been reported to act through TNF-R1 (6,7). In contrast, TNF-R2 appears to be important in T cell signaling and responses to infection (7,8). TNF-R2 binds to distinct members of the TRAF family, leading to the activation of NF-κB (9,10). Soluble forms of both receptors have also been characterized which can bind TNF-α and may play an important role in immune disorders (11,12).
