The ProQuantum HumanCEAImmunoassay Kit is designed to provide highly sensitive quantitative measurements of human CEA 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CEA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CEA (Carcino Embryonic Antigen, CD66e) is synthesized during development in the fetal gut, and re-expressed in increased amounts in intestinal carcinomas and several other tumors. CEA is a member of carcinoembryonic antigens, immunoglobulin supergene family and consists of a single N domain (structural homology to the immunoglobulin variable) and six immunoglobulin constant-like A (A1, A2, A3) and B domains (B1, B2, B3). Antibodies to CEA are useful in identifying the origin of various metastatic adenocarcinomas and in distinguishing pulmonary adenocarcinomas (60 to 70% are CEA+) from pleural mesotheliomas (rarely or weakly CEA+). CEA is a member of a large family of glycoproteins, a useful tumor marker for adenocarcinoma, and found in adenocarcinomas of endodermally derived digestive system epithelium and fetal colon. Two subgroups of the CEA family, the CEA cell adhesion molecules and the pregnancy-specific glycoproteins, are located within a 1.2 Mb cluster on the long arm of chromosome 19. Eleven pseudogenes of the CEA cell adhesion molecule subgroup are also found in the cluster. CEA was originally described in bile ducts of liver as biliary glycoprotein. Subsequently, CEA was found to be a cell-cell adhesion molecule detected on leukocytes, epithelia, and endothelia. The encoded protein mediates cell adhesion via homophilic as well as heterophilic binding to other proteins of the subgroup. Multiple cellular activities have been attributed to the encoded protein, including roles in the differentiation and arrangement of tissue three-dimensional structure, angiogenesis, apoptosis, tumor suppression, metastasis, and the modulation of innate and adaptive immune responses. Multiple transcript variants encoding different isoforms have been reported, but the full-length nature of all variants has not been defined.CEA(Carcino Embryonic Antigen,CD66e)是在胎儿肠道发育过程中合成的,并在肠癌和其他几种肿瘤中大量表达。 CEA是癌胚抗原(免疫球蛋白超基因家族)的成员,由一个N结构域(与免疫球蛋白变量具有结构同源性)和六个免疫球蛋白常数样A(A1,A2,A3)和B结构域(B1,B2,B3)组成。 CEA抗体可用于鉴定各种转移性腺癌的起源,还可用于区分胸膜间皮瘤(罕见或弱于CEA +)的肺腺癌(60%至70%为CEA +)。 CEA是糖蛋白大家族的成员,糖蛋白是腺癌的有用的肿瘤标志物,并且存在于真皮内衍生的消化系统上皮和胎儿结肠的腺癌中。 CEA家族的两个亚组,即CEA细胞粘附分子和妊娠特异性糖蛋白,位于19号染色体长臂的1.2 Mb簇中。在该簇中还发现了11个CEA细胞粘附分子亚组的假基因。 CEA最初在肝胆管中被描述为胆汁糖蛋白。随后,发现CEA是在白细胞,上皮和内皮上检测到的细胞粘附分子。编码的蛋白质通过与亚组其他蛋白质的同种和异种结合介导细胞粘附。多种细胞活性已经归因于编码的蛋白质,包括在组织三维结构的分化和排列,血管生成,细胞凋亡,肿瘤抑制,转移以及固有和适应性免疫应答的调节中的作用。已经报道了编码不同同工型的多个转录物变体,但是尚未定义所有变体的全长性质。For Research Use Only.
