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IFNγ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IFN gamma (Interferon gamma, Type II interferon) is a macrophage activation factor, and immune interferon that is produced primarily by T-lymphocytes and natural killer cells in response to antigens, mitogens, Staphylococcus enterotoxin B, phytohemaglutanin and other cytokines. IFN gamma is a dimeric protein consisting of two 146 amino acid subunits. IFN gamma is a glycoprotein that exists, functionally, as a homodimer of approximately 45 kDa. On SDS-PAGE, IFN gamma appears as a combination of 25, 20 and minor 15.5 kDa bands as a result of differential glycosylation. The biological activity of the IFN gamma homodimer is highly species specific. Human IFN gamma does not show cross-reactivity with mouse. IFN gamma function includes the following: antiviral activity, tumor antiproliferative activity, induction of class I and II MHC, macrophage activation, and enhanced immunoglobulin secretion by B lymphocytes. IFN gamma is involved in cytokine regulation and also acts synergistically with other cytokines. Activation of IFN gamma takes place through binding of IFN gamma receptor I and II, and activating the JAK-STAT pathway. IFN gamma does not show any homology with IFN alpha or IFN beta but human IFN gamma shows about 40% sequence homology with mouse IFN gamma. IFN gamma is upregulated by IL2, FGF basic, EGF and downregulated by vitamin D3 or DMN. IFN gamma gene mutations are associated with aplastic anemia.IFNγ(干扰素γ,II型干扰素)是一种巨噬细胞激活因子,是免疫干扰素,主要由T淋巴细胞和自然杀伤细胞响应抗原,促细胞分裂剂,葡萄球菌肠毒素B,植物血凝素和其他细胞因子而产生。 IFNγ是由两个146个氨基酸亚基组成的二聚体蛋白。 IFNγ是一种糖蛋白,功能上以约45 kDa的同型二聚体形式存在。在SDS-PAGE上,由于差异糖基化,IFNγ出现为25、20和较小的15.5 kDa条带的组合。 IFNγ同二聚体的生物活性是高度物种特异性的。人IFNγ与小鼠无交叉反应。 IFNγ功能包括:抗病毒活性,肿瘤抗增殖活性,I类和II类MHC的诱导,巨噬细胞活化以及B淋巴细胞增强的免疫球蛋白分泌。 IFNγ参与细胞因子的调节,并与其他细胞因子协同作用。 IFNγ的激活是通过结合IFNγI和II并激活JAK-STAT途径进行的。 IFNγ与IFNα或IFNβ没有任何同源性,但是人IFNγ与小鼠IFNγ显示约40%的序列同源性。 IFNγ被IL2,FGF碱性蛋白,EGF上调,而被维生素D3或DMN下调。 IFNγ基因突变与再生障碍性贫血有关。For Research Use Only.
