Monoclonal Antibody for studying DFNA5. Validated for Western Blotting,Immunofluorescence (Immunocytochemistry). Highly specific and rigorously validated in-house, Gasdermin E (E2X7E) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #19485) is ready to ship. Product Usage Information This product is the carrier free version of product #19453. 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 Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 19453 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 Gasdermin E (E2X7E) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total Gasdermin E protein. This antibody can also detect the amino-terminal cleavage fragment of Gasdermin E associated with pyroptosis. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human protein. Background The gasdermin family, which includes GSDMA, GSDMB, GSDMC, GSDMD, and GSDME, has been shown to play a role in inflammation and cell death. Gasdermin D has been reported to have a critical role as a downstream effector of pyroptosis (1,2). Pyroptosis is a lytic type of cell death triggered by inflammasomes, multiprotein complexes assembled in response to pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs) that result in the activation of caspase-1 and subsequent cleavage of pro-inflammatory cytokines IL-1β and IL-18 (3). Gasdermin D was identified by two independent groups as a substrate of inflammatory caspases, caspase-1 and caspase-11/4/5, producing two fragments: GSDMD-N and GSDMD-C. Cleavage results in release of an intramolecular inhibitory interaction between the N- and C-terminal domains, allowing the N-terminal fragment GSDMD-N to initiate pyroptosis through the formation of pores on the plasma membrane (4-7). Gasdermin E (GSDME), also known as DFNA5, was originally identified as a genetic cause of nonsyndromic hearing loss (8). Like other gasdermin family members, Gasdermin E contains an amino-terminal pore forming domain that triggers pyroptosis. Cleavage of Gasdermin E at Asp270 is induced by apoptotic-associated caspase-3, converting apoptotic signals to pyroptosis (9). In addition, cleavage of Gasdermin E can be induced by Granzyme B secreted by NK cells and contributes to tumor suppressive activity (10). Gasdermin E expression is suppressed in several types of cancer including gastric, colorectal, and breast carcinoma, and may be associated with decreased survival (11-13). In contrast, an increase in Gasdermin E, including the amino-terminal pore-forming fragment, is associated with conditions of excessive inflammation (14-16).
