An antibody specific for TNF\/TNFA\/TNFSF2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTNF\/TNFA\/TNFSF2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TNF\/TNFA\/TNFSF2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TNF\/TNFA\/TNFSF2 bound in the initial step. The color development is stopped and the intensity of the color is measured.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eProduct Overview\u003c\/b\u003e:TNFa  is synthesized as a 26 kDa, type II transmembrane protein that is 233 amino acids in length. It contains a 30 amino acid (aa) cytoplasmic domain, a 26 aa transmembrane segment, and a 177 aa extracellular region. TNFa is assembled intracellularly to form a transmembrane, non-covalently-linked homotrimeric protein. The 157 aa residue soluble form of TNFa (sTNF-αis released from the C-terminus of the transmembrane protein through the activity of TNFa-converting enzyme (TACE), a membrane -bound disintegrin metalloproteinase. Rat cells known to express TNF-αinclude B cells, colonic columnar epithelial cells, NK and CD3 CD56 hepatic natural T cells, macrophages, monocytes and monocyte-derived dendritic cells, CD4 and CD8 T cells, mast cells, neutrophils, keratinocytes, plasma cells, and adipocytes.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStability\u003c\/b\u003e:The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. \nThe loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).\u003c\/p\u003e","brand":"Gene Bio Systems","offers":[{"title":"Default Title","offer_id":39784271052900,"sku":"AE14049PI","price":834.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/products\/no_image_default_image-jpeg_95e65958-a5fb-4eb0-9ac5-d302a1ddc744.jpg?v=1659154152","url":"https:\/\/www.genebiosystems.com\/en-gb\/products\/pig-tumor-necrosis-factor-tnf-tnfa-tnfsf2-elisa-kit-1","provider":"GeneBio ","version":"1.0","type":"link"}
