| The Human High Sensitivity Interleukin 17A (HS IL-17A) ELISA quantitates Hu HS IL-17A in human serum, plasma, buffered solution, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu HS IL-17A.人白介素17A（HS IL-17A）高灵敏度ELISA定量了人血清，血浆，缓冲溶液或细胞培养基中的人HS IL-17A。 该检测试剂盒将专门识别天然和重组的人HS IL-17A。Principle of the method 方法原理TheHuman HS IL-17Asolid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A special amplification reagent step is added to achieve the high sensitivity capability. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.人 HS IL-17A固相夹心ELISA（酶联免疫吸附测定）用于测量匹配的抗体对之间结合的靶标量。 已在孔中预包被了靶标特异性抗体。 然后将样品，标准液或质控品添加到这些孔中，并与固定的（捕获）抗体结合。 添加了特殊的扩增试剂步骤以实现高灵敏度。 经过孵育和洗涤步骤以去除微孔板中未结合的物质后，添加底物溶液，该溶液与酶-抗体-靶标复合物反应以产生可测量的信号。 该信号的强度与原始样品中存在的靶标浓度成正比。 Rigorous validation 严格验证 Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency.

IL-17A is a 32 kDa long, disulfide-linked homodimer consisting of 136 amino acids that is a member of a six-species family of proteins (IL-17A-17F) and signals through the IL-17 receptor (IL-17R/CDw217). High levels of IL-17A homodimer are produced by activated peripheral blood CD4+ T-cells, and IL-17A also enhances expression of the intracellular adhesion molecule-1 (ICAM-1) in human fibroblasts. In particular, human IL-17A also stimulates epithelial, endothelial, or fibroblastic cells to secrete IL-6, IL-8, G-CSF, and PGE2. In the presence of human IL-17A, fibroblasts can sustain the proliferation of CD34+ hematopoietic progenitors and induce maturation into neutrophils. Mouse, rat, and human IL-17A can induce IL-6 secretion in mouse stromal cells, indicating that all homologs can recognize the mouse receptor. IL-17A regulates the activities of NF-kappa B and mitogen-activated protein kinases, stimulates the expression of IL-6 and cyclooxygenase-2 (PTGS2/COX-2), and enhances the production of nitric oxide (NO).白介素-17A（IL-17A，CTLA-8）是CD4 + T细胞衍生的细胞因子，可促进细胞系中的炎症反应，并在类风湿性关节炎，哮喘，多发性硬化症，牛皮癣和移植排斥反应中升高。 IL-17A是一种32 kDa长的二硫键连接的同型二聚体，由136个氨基酸组成，是六种蛋白质家族（IL-17A-17F）的成员，并通过IL-17受体（IL-17R / CDw217）。活化的外周血CD4 + T细胞产生高水平的IL-17A同型二聚体，并且IL-17A还增强人成纤维细胞中细胞内粘附分子1（ICAM-1）的表达。特别地，人IL-17A还刺激上皮，内皮或成纤维细胞分泌IL-6，IL-8，G-CSF和PGE2。在人IL-17A存在的情况下，成纤维细胞可以维持CD34 +造血祖细胞的增殖并诱导成熟为嗜中性粒细胞。小鼠，大鼠和人IL-17A可以诱导小鼠基质细胞中的IL-6分泌，这表明所有同源物都可以识别小鼠受体。 IL-17A调节NF-κB和丝裂原激活的蛋白激酶的活性，刺激IL-6和环氧合酶2（PTGS2 / COX-2）的表达，并增强一氧化氮（NO）的产生。For Research Use Only.
