Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nCaspase-1, or interleukin-1ß converting enzyme (ICE\/ICEα), is a class I cysteine protease, which also includes caspases -4, -5, -11, and -12. Caspase-1 cleaves inflammatory cytokines such as pro-IL-1ß and interferon-γ inducing factor (IL-18) into their mature forms (1,2). Like other caspases, caspase-1 is proteolytically activated from a proenzyme to produce a tetramer of its two active subunits, p20 and p10. Caspase-1 has a large amino-terminal pro-domain that contains a caspase recruitment domain (CARD). Overexpression of caspase-1 can induce apoptosis (3). Mice deficient in caspase-1, however, have no overt defects in apoptosis but do have defects in the maturation of pro-IL-1β and are resistant to endotoxic shock (4,5). At least six caspase-1 isoforms have been identified, including caspase-1 α, β, γ, δ, ε, and ζ (6). Most caspase-1 isoforms (α, β, γ, and δ) produce products between 30-48 kDa and induce apoptosis upon overexpression. Caspase-1 ε typically contains only the p10 subunit, does not induce apoptosis, and may act as a dominant negative. The widely expressed ζ isoform of caspase-1 induces apoptosis and lacks 39 amino-terminal residues found in the α isoform (6). Activation of caspase-1 occurs through an oligomerization molecular platform designated the \"inflammasome\" that includes caspase-5, Pycard\/Asc, and NALP1 (7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCASP-1; CASP1; CASP1 nirs variant 1; Caspase 1; caspase 1, apoptosis-related cysteine peptidase; caspase 1, apoptosis-related cysteine peptidase (interleukin 1, beta, convertase); caspase 1, apoptosis-related cysteine protease (interleukin 1, beta, convertase); Caspase-1; Caspase-1 subunit p10; Caspase-1 subunit p20; caspase1; Caspase1; ICE; IL-1 beta-converting enzyme; IL-1BC; IL1B-convertase; IL1BC; IL1BCE; interleukin 1-B converting enzyme; interleukin 1-beta convertase; interleukin 1, beta, convertase; Interleukin-1 beta convertase; Interleukin-1 beta-converting enzyme; p45\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 20 p20. 30 to 45 beta, delta, gamma. 50 alpha.\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46797660618921,"sku":"2225S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2225s","provider":"Iright","version":"1.0","type":"link"}
