随着免疫学和癌症生物学的进步,人们对越来越敏感的系统来监测特定细胞标志物的表达以开发新的诊断和治疗工具的需求尚未得到满足。为了应对这一挑战,我们应用了一种高度灵敏的标记方法,该方法将抗原-抗体识别过程转化为DNA检测事件,该事件可以通过等温滚环扩增(RCA)大大扩增。通过将RCA反应的单分子检测能力与微流体技术相结合,我们能够证明可以在微型化的纳升反应液滴中在肿瘤细胞表面上实现特异性蛋白质标志物的鉴定。此外,这种以微流体形式进行信号放大的组合方法可以通过减少样品和试剂消耗并增强各种应用(包括癌症的早期诊断)的灵敏度和特异性来扩展现有方法的实用性。
With advances in immunology and cancer biology, there is an unmet need for increasingly sensitive systems to monitor the expression of specific cell markers for the development of new diagnostic and therapeutic tools. To address this challenge, we have applied a highly sensitive labeling method that translates antigen-antibody recognition processes into DNA detection event that can be greatly amplified via isothermal Rolling Circle Amplification (RCA). By merging the single-molecule detection power of RCA reaction with microfluidic technology we were able to demonstrate that identification of specific protein markers can be achieved on tumor cell surface in miniaturized nano-liter reaction droplets. Furthermore, this combined approach of signal amplification in a microfluidic format could extend the utility of existing methods by reducing sample and reagent consumption and enhancing the sensitivities and specificities for various applications, including early diagnosis of cancer.
