【背景介绍】白细胞介素10(IL-10)是由2个长178个氨基酸的亚基构成的同源二聚体。在人类中,它由位于1号染色体的IL10基因编码,由5个外显子组成。IL-10主要由单核细胞分泌,淋巴细胞、II型辅助性T细胞(Th2)、肥大细胞、CD4+CD25+Foxp3+调节性T细胞和部分活化的T细胞和B细胞分泌较少。它对免疫调控和炎症具有多种效应。它下调巨噬细胞的Th1细胞因子、II类MHC抗原和共刺激分子。它还能增强B细胞存活、增殖和抗体分泌。IL-10能阻断NF-κB活性,并参与JAK-STAT信号通路调控。IL-10的免疫抑制特性提示其可能应用于临床,抑制器官移植后的排斥。IL-10还具有强烈的消炎特性。
【DESCREPTION】The IL-10 protein is a homodimer, each of its subunits is 178-amino-acid long. In humans, IL-10 is encoded by the IL10 gene, which is located on chromosome 1 and comprises 5 exons, and is primarily produced by monocytes and, to a lesser extent, lymphocytes, namely type 2 T helper cells (Th2), mastocytes, CD4+CD25+Foxp3+ regulatory T cells, and in a certain subset of activated T cells and B cells. IL-10 is a cytokine with multiple, pleiotropic, effects in immunoregulation and inflammation. It downregulates the expression of Th1 cytokines, MHC class II antigens, and co-stimulatory molecules on macrophages. It also enhances B cell survival, proliferation, and antibody production. IL-10 can block NF-κB activity, and is involved in the regulation of the JAK-STAT signaling pathway. The immunosuppressive properties of IL-10 suggest a possible clinical use of IL-10 in suppressing rejections of grafts after organ transplantations. IL-10 can furthermore exert strong anti-inflammatory activities.
【检测原理】本试剂盒采用双抗体夹心酶联免疫吸附检测技术。特异性抗人IL-10单克隆抗体预包被在高亲和力的酶标板上。酶标板孔中加入标准品和待测样本,经过孵育,样本中存在的IL-10与固相抗体结合。洗涤去除未结合的物质后,加入生物素化的检测抗体孵育。洗涤去除未结合的生物素化的抗体,加入辣根过氧化物酶标记的链霉亲和素(Streptavidin-HRP)。洗涤后,加入信号增强剂孵育,洗涤去除未结合的物质后,再次加入streptavidin-HRP。洗涤后,加入显色底物TMB,避光显色。颜色反应的深浅与样本中IL-10的浓度成正比。加入终止液终止反应,在450nm波长(参考波长570-630nm)测定吸光度值。
【PRINCIPLE OF THE ASSAY】This assay employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for human IL-10 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and IL-10 present is bound by the immobilized antibody. After washing away any unbound substances, a biotin-linked detect antibody specific for IL-10 is added to the wells. Following a wash to remove any unbound antibody-biotin reagent, streptavidin-HRP is added. After washing, amplification reagent is added to the wells. Following incubation any unbound substances is removed during a wash step and streptavidin-HRP is added. After washing, substrate solution is added to the wells and color develops in proportion to the amount of IL-10 bound in the initial step. The color development is stopped and the intensity of the color is measured.
