Simoa单分子免疫阵列超灵敏细胞因子
检测服务
产品介绍：
SimoaTM（Single Molecular Array）又称作数字式ELISA，是基于Simoa HD-1数字式单分子免疫阵列分析仪，可直接对血清和血浆中蛋白、核酸等生物标志物进行检测的技术。它的检测灵敏度比传统的免疫检测技术平均高1000倍以上，将蛋白质检测技术直接带入单分子、数字化检测时代，成为fg级超低丰度蛋白质检测领域的优势技术。
技术原理：
1、将捕获抗体偶联到磁珠上，磁珠与目标抗原结合，目的抗原与检测抗体结合并带有梅标记。
2、洗涤磁珠以去除非特异性结合的蛋白，加入酶反应底物。
3、将加入底物的磁珠转入Simoa光盘上，将荧光信号封闭在小孔内。
应用领域：
Simoa技术可用于肿瘤、神经、感染性疾病、免疫炎症、miRNA检测，特别是癌症的早期检测、术后的监测和精准用药，将极大推动精准医疗的发展。运用Simoa可检测到的低浓度生物标志物进行准确分析，为生命科学研究、体外诊断、伴随诊断和血液筛查等领域。目前在全球引用该技术发表的文献有200多篇，包括高分杂志Nature, Nature Biotechnology, JEM, JAMA Neurology等。
