| The ProQuantum Human IL-12 p40 Immunoassay Kit is designed to provide highly sensitive quantitative measurements of human IL-12 p40 protein in small sample volumes. Utilizing proximity ligation assay (PLA) technology, the assay combines the analyte specificity of high-affinity antibody-antigen binding with the signal detection and amplification capabilities of real-time PCR to achieve a simple yet powerful next-generation protein quantitation platform. A user-friendly workflow combined with intuitive Cloud-based software for analytics enables sample-to-answer in just 2 hours.ProQuantum 免疫检测试剂盒进行少量人IL-12 p40蛋白的高灵敏度定量检测。 利用邻近连接测定（PLA）技术，该测定将高亲和力抗体-抗原结合的分析物特异性与实时PCR的信号检测和扩增功能结合在一起，从而实现了一个简单而强大的下一代蛋白质定量平台。 友好的工作流程与直观的基于云的分析软件相结合，可在2小时内完成从样品到答案的分析。ProQuantum immunoassays utilize a matched pair of target-specific antibodies, each conjugated to a DNA oligonucleotide. During antibody-analyte binding, the two DNA oligos are brought into close proximity, which allows for ligation of the two strands and subsequent creation of a template strand for amplification. This platform leverages the sensitivity and large dynamic range of Applied Biosystems TaqMan real-time PCR technology.ProQuantum免疫测定法使用一对配对的靶标特异性抗体，每种抗体均与DNA寡核苷酸偶联。 在抗体-分析物结合过程中，两个DNA寡核苷酸紧密靠近，这允许两条链连接并随后创建模板链进行扩增。 该平台利用了Applied Biosystems TaqMan实时PCR技术的灵敏度和宽动态范围。The assay workflow is fast and easy—2 steps in 2 hours. There are a total of 7 components in each kit (Figure 2). First, mix the antibody-conjugates, dilute the sample, and create the standard curve in a working plate. Then, using a multi-channel pipette, add the antibody-conjugates and sample (or standard) into the wells of a PCR plate and incubate for 1 hour. Combine the master mix and ligase and add to the wells of the PCR plate, then run the plate on any qPCR instrument. After the run is complete, import the results file into the ProQuantum cloud-based software at https://apps.thermofisher.com/apps/proquantum. Using this software, the data can be analyzed easily to obtain protein concentration values. The software allows you to set up standard curves, design plate layouts, set up customized assay instructions, and obtain robust statistical group-wise comparisons.测定工作流程快速简便— 2小时内完成2个步骤。 每个试剂盒中总共有7个组件。 首先，混合抗体-结合物物，稀释样品，并在工作板上创建标准曲线。 然后，使用多通道移液器，将抗体结合物和样品（或标准品）添加到PCR板的孔中，并孵育1小时。 合并预混液和连接酶，并添加到PCR板的孔中，然后在任何qPCR仪器上运行该板。 运行完成后，将结果文件导入https://apps.thermofisher.com/apps/proquantum的基于ProQuantum云的软件中。 使用此软件，可以轻松分析数据以获得蛋白质浓度值。 该软件允许您设置标准曲线，设计板布局，设置定制化验说明并获得可靠的逐组统计比较。Target information 靶标信息Interleukin-12 (IL-12) is a heterodimeric 70 kD (p70) cytokine composed of two covalently linked, glycosylated chains, 40kD (p40) and 35-kD (p35). IL-12 is mainly produced by monocytes, macrophages, and dendritic cells in response to bacterial products such as lipopolysaccharides (LPS), to intracellular pathogens or upon interaction with activated T cells. IL-12 was originally discovered because of its ability to induce interferon-gamma production, cell proliferation, and cytotoxicity mediated by natural killer cells and T cells. It is now established that IL-12 also plays a key role in the development of Th1 responses, leading to IFN-gamma and IL-2 production. These cytokines can in turn promote T-cell responses and macrophage activation. The p40 and p35 subunits by themselves have no IL-12 bioactivity, though the p40 homodimer has been shown to bind the IL-12 receptor and to be an antagonist of IL-12 p70. Free p40 is typically secreted in vast excess of IL-12 p70 by cells co-expressing both the p35 and p40 subunits. The p40 subunit of IL-12 has been shown to have extensive amino acid sequence homology to the extracellular domain of the IL-6 receptor, while the p35 subunit shows some homology to IL-6 and G-CSF.白介素12（IL-12）是一种异源二聚体70 kD（p70）细胞因子，由两条共价连接的糖基化链40kD（p40）和35-kD（p35）组成。 IL-12主要由单核细胞，巨噬细胞和树突状细胞响应细菌产品（如脂多糖（LPS）），细胞内病原体或与活化T细胞相互作用而产生。最初发现IL-12是因为它具有诱导干扰素-γ产生，细胞增殖以及由自然杀伤细胞和T细胞介导的细胞毒性的能力。现在已经确定，IL-12在Th1反应的发展中也起着关键作用，导致IFN-γ和IL-2的产生。这些细胞因子继而可以促进T细胞反应和巨噬细胞活化。尽管已经显示p40同型二聚体结合IL-12受体并且是IL-12 p70的拮抗剂，但是p40和p35亚基本身没有IL-12的生物活性。共表达p35和p40亚基的细胞通常会在IL-12 p70的大量过量中分泌出游离p40。已显示IL-12的p40亚基与IL-6受体的胞外域具有广泛的氨基酸序列同源性，而p35亚基与IL-6和G-CSF具有某些同源性。For Research Use Only.

| IL-12 p40Human ProQuantum Immunoassay Kit<b>How ProQuantum immunoasssays work</b><br />(A) Antibody-antigen binding: Antibodies bind to two separate epitopes on the antigen (during a 1-hr incubation), which brings the two conjugated oligonucleotides into close proximity. (B) Ligation and amplification of signal (in a qPCR instrument): DNA ligase and a third splint oligonucleotide connector are added to ligate the two ends of the conjugated oligonucleotides, creating a 100-base DNA template. Once the ligase is inactivated at 95°C, the sample is amplified through 40 cycles of annealing and extension. The amount of DNA produced is measured after each amplification cycle via fluorescent dyes, which exhibit fluorescence that is directly proportional to the number of PCR product molecules (or amplicons) generated. This graph shows the fluorescence vs. cycle number curves for four different starting protein concentrations. The dashed line represents the fluorescence threshold. The cycle number required to reach the fluorescence threshold (threshold cycle or Ct) is plotted vs. protein concentration to create a standard curve.<b> ProQuantum免疫测定的工作原理</ b> <br />（A）抗体-抗原结合：抗体与抗原上的两个独立表位结合（在1小时的孵育过程中），这使两个结合的寡核苷酸紧密相邻。 （B）信号的连接和扩增（在qPCR仪器中）：添加DNA连接酶和第三个夹板寡核苷酸连接物以连接缀合的寡核苷酸的两端，从而产生100个碱基的DNA模板。连接酶在95°C失活后，样品会通过40个退火和延伸循环进行扩增。在每个扩增循环后，通过荧光染料测量产生的DNA量，该荧光染料显示的荧光与产生的PCR产物分子（或扩增子）的数量成正比。该图显示了四种不同起始蛋白浓度的荧光与循环数曲线。虚线表示荧光阈值。将达到荧光阈值所需的循环数（阈值循环或Ct）对蛋白质浓度作图，以创建标准曲线。 IL-12 p40 Human ProQuantum Immunoassay Kit<b>ProQuantum kit contents</b><br />Components are color coded for ease of use. |
