Validated for Western Blotting,Immunofluorescence (Immunocytochemistry),Flow Cytometry (Fixed\/Permeabilized). Highly specific and rigorously validated in-house, NF-kappaB1 p105\/p50 (D4P4D) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #83394) is ready to ship.\n\n\u003cb\u003eProduct Usage Information\u003c\/b\u003e\nThis product is the carrier free version of product #13586. 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\u0026amp;RUN or CUT\u0026amp;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.\n\u003cb\u003eFormulation\u003c\/b\u003e\nSupplied 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 # 13586 .\n\u003cb\u003eStorage\u003c\/b\u003e\nStore 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.\n\u003cb\u003eSpecificity \/ Sensitivity\u003c\/b\u003e\nNF-kappaB1 p105\/p50 (D4P4D) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of total NF-κB1 p105\/p50 protein.\nSpecies Reactivity: Human, Mouse, Rat\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ile415 of mouse NF-κB1 p105\/p50 protein.\n\u003cb\u003eBackground\u003c\/b\u003e\nTranscription factors of the nuclear factor κB (NF-κB)\/Rel family play a pivotal role in inflammatory and immune responses (1,2). There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105\/p50), and NF-κB2 (p100\/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus (9-11). Following IKK-mediated phosphorylation of p105 NF-κB at multiple sites (Ser921, 923, 927, and 932) on its carboxy terminus, SCF\/β-TrCP-mediated processing produces the 50 kDa active form p50 (12,13).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nDNA-binding factor KBF1; EBP-1; NF kappaB1; NF-k; NF-kappa-B1 p84\/NF-kappa-B1 p98; NF-kappaB; NF-kappaB p50; NF-kappaB1; NF-KB1; NFkB-p105; Nfkb1; nuclear factor kappaB p50; Nuclear factor NF-kappa-B p105 subunit; Nuclear factor NF-kappa-B p50 subunit; nuclear factor of kappa light chain gene enhancer in B-cells 1, p105; nuclear factor of kappa light polypeptide gene enhancer in B cells 1, p105; Nuclear factor of kappa light polypeptide gene enhancer in B-cells 1; nuclear factor of kappa light polypeptide gene enhancer in B-cells 1, p105; nuclear factor-kappaB p50; OTTMUSP00000018024; p105; p50; p50 subunit of NF kappaB; p50 subunit of NF-kappaB; p50\/p1; p50\/p105\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 50 Active form. 120 Precursor\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799937339561,"sku":"83394SF","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-83394sf","provider":"Iright","version":"1.0","type":"link"}
