我们提出了一种利用DNA标记抗体和液滴微流控技术测量单细胞中基因和蛋白质表达水平的工具。通过RNA表达和蛋白质测序分析(REAP - seq),我们在单个工作流程中使用82种带条形码的抗体对蛋白质进行了定量,并对超过20,000个基因进行了分析。我们利用REAP - seq评估了一种CD27激动剂对人CD8(+)淋巴细胞的共刺激效应,并识别和鉴定了一种未知的细胞类型。
We present a tool to measure gene and protein expression levels in single cells with DNA-labeled antibodies and droplet microfluidics. Using the RNA expression and protein sequencing assay (REAP-seq), we quantified proteins with 82 barcoded antibodies and > 20,000 genes in a single workflow. We used REAP-seq to assess the costimulatory effects of a CD27 agonist on human CD8(+) lymphocytes and to identify and characterize an unknown cell type.
