We present a method for the quantification of small regulatory RNAs (sRNAs) in bacteria, by combining single-molecule fluorescence in situ hybridization (smFISH), super-resolved single-fluorophore microscopy, and clustering analysis. Compared to smFISH imaging with diffraction-limited fluorescence microscopy, our method provides better quantification for short and abundant RNA (such as sRNAs) in a small volume of bacterial cells. Our method can also be directly used for the quantification of messenger RNAs (mRNAs).
我们提出了一种通过结合单分子荧光原位杂交（smFISH）、超分辨单荧光团显微镜和聚类分析来定量细菌中小调节RNA（sRNA）的方法。与使用衍射极限荧光显微镜的smFISH成像相比，我们的方法能更好地定量少量细菌细胞中的短且丰富的RNA（如sRNA）。我们的方法也可直接用于信使RNA（mRNA）的定量。
