细胞群的膜抗原表达分析在临床应用和基础生物学研究中常规需要。在这项工作中,我们介绍了一种微流控装置,其目的是以电子方式分析给定细胞群中的表面抗原密度,作为荧光激活细胞分选仪的低成本替代品。通过将磁泳细胞分选与代码复用电阻脉冲传感器阵列耦合,我们的设备可以在分选过程中对细胞的磁偏转进行电量化。使用人乳腺癌细胞系的实验证明了该装置在异质细胞群分析中的实用性。
Membrane antigen expression analysis of a cell population is routinely needed in clinical applications and basic biology research. In this work, we introduce a microfluidic device that aims to electronically profile the surface antigen density in a given cell population as a low-cost alternative to fluorescent-activated cell sorter. By coupling magnetophoretic cell sorting with an array of code-multiplexed resistive pulse sensors, our device can electrically quantify magnetic deflection of cells in the sorting process. Experiments using human breast cancer cell line demonstrate the utility of this device in the analysis of heterogeneous cell populations.
