简介：
Overview
Single molecule RNA fluorescence in situ hybridization (smFISH) is a powerful technique for quantifying RNA levels and localization at the single cell level. This method enables the analysis of cell-to-cell and allele-by-allele variation in RNA, providing insights into gene transcription and RNA response to external stimuli.
