Abstract

The prevalence of autoimmune diseases affect millions of patients worldwide and its incidence has increased over the years. Here we report on the use of a microfluidic device and homemade portable integrated real-time PCR (qPCR) device for the quantification of tumor necrosis factor-α (TNF-α) at the point-of-care (POC). Our device is a disposable cyclic polyolefin (COP)-based microfluidic chip, and the assay is a magnetic bead-based proximity ligation assay. The data presented herein show on-chip TNF-α quantification within the clinically relevant range of 5-100 pg/ml in both buffer and human plasma. Further development could lead to a potential method for monitoring anti-inflammatory therapy.
一种用于人血浆中TNF-α定量的微流控磁珠接近结扎试验装置
自身免疫性疾病的流行影响着全世界数百万患者,其发病率多年来一直在增加。在这里,我们报告了使用微流控装置和自制便携式集成实时荧光定量PCR (qPCR)装置在护理点(POC)定量肿瘤坏死因子-α (TNF-α)。我们的设备是一种基于一次性循环聚烯烃(COP)的微流控芯片,该检测是一种基于磁珠的接近连接检测。本文提供的数据显示,缓冲液和人血浆中芯片上TNF-α的定量在5-100 pg/ml的临床相关范围内。进一步的发展可能会导致一种潜在的方法来监测抗炎治疗。
