【项目简介】
Interleukin-18 receptor 1 (IL18R1) also known as CD218 antigen-like family member A, CDw218a, IL1 receptor-related protein and CD218a, is an interleukin receptor of the immunoglobulin superfamily. IL18R1 is found expressed in lung, leukocytes, spleen, liver, thymus, prostate, small intestine, colon, placenta, and heart, and is absent from brain, skeletal muscle, pancreas, and kidney. High level of expression is found in Hodgkin disease cell lines. This receptor is specifically binds interleukin 18 (IL18), and is essential for IL18 mediated signal transduction. IL18R1 contains 3 Ig-like C2-type (immunoglobulin-like) domains and 1 TIR domain. It is a single-pass type I membrane protein. IFN-alpha and IL12 are reported to induce the expression of this receptor in NK and T cells. The increased expression of IL18R1 may contribute pathogenically to disease and is therefore a potential therapeutic target. The absence of a genetic association in the IL18R1 gene itself suggests regulation from other parts of the genome, or as part of the inflammatory cascade in multiple sclerosis without a prime genetic cause.
 
【检验原理】
本试剂盒采用双抗体夹心ELISA法。酶标微孔板上预包被有抗小鼠IL18R1抗体,当加入标准品和待测样本时,标准品和待测样本中的小鼠IL18R1会和该抗体结合。洗板后,游离的其他成分被洗去,加入辣根过氧化物酶标记的的抗小鼠IL18R1抗体可与被酶标板捕获的小鼠IL18R1结合,形成“包被抗小鼠IL18R1抗体+小鼠IL18R1+抗小鼠IL18R1抗体-HRP”免疫复合物。当加入TMB显色底物后,复合物上连接的HRP催化底物反应,生成蓝色产物,终止反应后变为黄色。在450nm处测定OD值,小鼠IL18R1浓度与OD450值之间呈正比,可通过绘制标准曲线求出标本中小鼠IL18R1的浓度。
