纳升大小的液滴技术与数字PCR(ddPCR)相结合,有望实现高度精确的绝对核酸定量。我们通过ddPCR和实时PCR对microRNA定量进行的比较显示,ddPCR的精确度更高(变异系数降低了37-86%),日常重现性也有所提高(7倍),但灵敏度相当。当我们将ddPCR应用于血清microRNA生物标志物分析时,这转化为识别癌症个体的上级诊断性能。
Nanoliter-sized droplet technology paired with digital PCR (ddPCR) holds promise for highly precise, absolute nucleic acid quantification. Our comparison of microRNA quantification by ddPCR and real-time PCR revealed greater precision (coefficients of variation decreased by 37–86%) and improved day-to-day reproducibility (by a factor of seven) of ddPCR but with comparable sensitivity. When we applied ddPCR to serum microRNA biomarker analysis, this translated to superior diagnostic performance for identifying individuals with cancer.
