Nori Rat TNF RI ELISA Kit
$461.00 – $832.00
This ELISA kit is for quantification of TNFRI in rat. This is a quick ELISA assay that reduces time to 50% compared to the conventional method, and the entire assay only takes 3 hours. This assay employs the quantitative sandwich enzyme immunoassay technique and uses biotin-streptavidin chemistry to improve the performance of the assays. An antibody specific for TNFRI has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TNFRI present is bound by the immobilized antibody. After washing away any unbound substances, a detection antibody specific for TNFRI is added to the wells. Following wash to remove any unbound antibody reagent, a detection reagent is added. After intensive wash a substrate solution is added to the wells and color develops in proportion to the amount of TNFRI bound in the initial step. The color development is stopped, and the intensity of the color is measured.

Background:
Tumor necrosis factor receptor 1 (TNFR1), also known as tumor necrosis factor receptor superfamily member 1A (TNFRSF1A) and CD120a, is a ubiquitous membrane receptor that binds tumor necrosis factor-alpha (TNFα).[1] The protein is a member of the tumor necrosis factor receptor superfamily, which also contains TNFRSF1B. TNFR1 is one of the major receptors for the tumor necrosis factor-alpha. This receptor can activate the transcription factor NF-κB, mediate apoptosis, and function as a regulator of inflammation. Antiapoptotic protein BCL2-associated athanogene 4 (BAG4/SODD) and adaptor proteins TRADD and TRAF2 have been shown to interact with this receptor, and thus play regulatory roles in the signal transduction mediated by the receptor.[2] Germline mutations of the extracellular domains of this receptor were found to be associated with the human genetic disorder called tumor necrosis factor associated periodic syndrome (TRAPS) or periodic fever syndrome.[3] Impaired receptor clearance is thought to be a mechanism of the disease. Mutations in the TNFRSF1A gene is associated with elevated risk of multiple sclerosis. Serum levels of TNFRSF1A are elevated in schizophrenia and bipolar disorder,[4] and high levels are associated with more severe psychotic symptoms.[5] High serum levels is also associated with cognitive impairment and dementia.[6][7] TNFR1 is an ATPase regulated by silencer of death domain.[8]
