It uses our proprietary SimpleStep ELISA® technology. Quantitate Human IRF3 with 2.9 pg\/mL sensitivity.\u003cbr\u003e\nSimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:\u003cbr\u003e\n-Single-wash protocol reduces assay time to 90 minutes or less\u003cbr\u003e\n-High sensitivity, specificity and reproducibility from superior antibodies\u003cbr\u003e\n-Fully validated in biological samples\u003cbr\u003e\n-96-wells plate breakable into 12 x 8 wells strips\u003cbr\u003e\nA 384-well SimpleStep ELISA® microplate (\u003cbr\u003e\nab203359\u003cbr\u003e\n) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.\u003cbr\u003e\nIRF3, Interferon regulatory factor 3, is a transcription factor which plays a primary role in innate immunity. In the course of viral infection IRF3 will be phosphorylated, dimerize, and translocate to the nucleus where it regulates transcription of type I IFN genes. The immunogen from which the antibodies in this kit were raised represent the full-length protein. This protein shares only 70% and 73% sequence identity with mouse and rat, respectively, and is not expected to be highly cross-reactive.\u003cbr\u003e\nREACH authorisation\u003cbr\u003e\nAbcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.\u003cbr\u003e\nIt is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nIRF5 or Interferon Regulatory Factor 5 is a member of the IRF family of transcription factors. This protein weighs approximately 56 kDa and is expressed in cells of the immune system including B cells dendritic cells and macrophages. IRF5 plays an important role in regulating the transcription of interferon-stimulated genes following a viral infection. It acts by binding to specific DNA sequences initiating transcription processes that are important for the antiviral response.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nIRF5 influences the immune response through the regulation of cytokine production. It activates genes involved in producing pro-inflammatory cytokines such as TNF-α and IL-6 which are important for clearing viral infections and activating immune cells. IRF5 does not usually form part of a protein complex but it interacts closely with TRAF6 and MyD88 for its activation. Its pivotal role in cytokine production highlights its importance in controlling inflammation.\u003cbr\u003e\nPathways\u003cbr\u003e\nIRF5 is an important component of the Toll-like receptor (TLR) signaling pathway and plays a role in the MyD88-dependent pathway. In this context IRF5 gets activated by TLRs interacting with MyD88 and TAK1 to enhance the transcription of important genes for immune response. It is also closely connected to the IRF3 protein which shares similar activation pathways and can similarly initiate an antiviral state.\u003cbr\u003e\nDefects or dysregulation in IRF5 function are linked to autoimmune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis. In SLE IRF5 influences autoantibody production contributing to disease development. It works alongside other regulatory proteins involved in autoimmunity including IFN-α and STAT4 which also play significant roles in modulating immune responses. Understanding IRF5's role in these conditions could present new opportunities for therapeutic interventions using IRF5 inhibitors.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843584970921,"sku":"ab283551","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab283551","provider":"Iright","version":"1.0","type":"link"}
