| 描述 | PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant human IL6R antigen has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Tocilizumab in the sample competitively binds to the pre-coated protein with biotin-labeled Tocilizumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Tocilizumab bound in the initial step. The color development is stopped and the intensity of the color is measured. | ||||||||||||||||||||||||||||||||||||||||||

| 背景 | Tocilizumab is a humanized IgG1 monoclonal antibody to the IL-6 receptor that is used largely as therapy of refractory rheumatoid arthritis and other inflammatory arthritides. Tocilizumab blocks the action of IL-6, which is a key proinflammatory cytokine that mediates a wide spectrum of biologic activities including activation of T cells, differentiation of B cells, induction of acute phase reactants, proliferation of fibroblasts, and damage to cartilage and joints. IL-6 levels are elevated in patients with active rheumatoid arthritis. In controlled trials and open label studies, tocilizumab therapy led to improvements in symptoms and laboratory abnormalities associated with several forms of inflammatory arthritis. Tocilizumab was approved for use in the United States in 2010 and current indications include rheumatoid arthritis, giant cell arteritis and both the polyarticular and systemic forms of juvenile idiopathic arthritis (formerly juvenile rheumatoid arthritis). Tocilizumab is considered a disease modifying antirheumatic drug (DMARD) and improves signs and symptoms of disease and decreases cartilage and tissue destruction. | ||||||||||||||||||||||||||||||||||||||||||

文献和实验市面上的 ELISA 试剂盒五花八门，质量良莠不齐。如何浪里淘金，选择既符合科研需求，又品质上乘的 ELISA 试剂盒呢? 教你七招，快速搞定 ELISA 试剂盒的选择！ 01 查找待测样本的蛋白浓度 通过检索 SCI 文献、Genecards、Mayocliniclabs 等，获得目标蛋白的表达部位及表达浓度参考值，比较 ELISA 试剂盒中给出的样本测值与参考值是否一致。 02 明确试剂盒的应用种属＆检测的样本类型 不同厂家验证的样本类型不同。除试剂盒特别说明外，一般情况下，不同
本文主要介绍 ELISA 试剂盒、实验样本、相关问题，帮助大家更好地开展实验 试剂盒 Q1：科研试剂盒与临床试剂盒的区别 ？ A1：临床试剂是经过权威机构认可的，如 FDA、CFDA 等；而科研试剂一般是厂家自主研制，不需要通过权威机构验证。 经营临床诊断类产品的机构需要取得《医疗器械经营企业许可证》；经营科研试剂的机构不需要此证件。 临床试剂盒一般仅用于检测人血清/血浆等较为单一的分泌性样本类型；科研试剂盒的样本检测种类、检测范围则比临床试剂盒宽广得多。但一般来说，临床试剂盒的质量
目前市场上的 ELISA 试剂盒质量参差不齐，如何去挑选适合自己的试剂盒就显得特别重要，具体有以下几点可供参考。 特异性 ELISA 试剂盒的特异性与试剂盒的关键组分，抗体对有关。若抗体对中之一为多抗，另一个必须为单抗，建议使用双单抗。 灵敏度 灵敏度反映的是试剂盒检出被检物质的最低量的能力，用户可根据自己样本中待检指标的量选择合适的试剂盒，如果待检指标量很低，一般的试剂盒不能满足要求，可选择高敏的 ELISA 试剂盒。 重复
