Hence, quantitative measurement of noise in gene expression is essential for the study of biological processes in cells. Currently, there are two complementary methods for quantitatively measuring noise in gene expression at the single cell level: single molecule FISH (smFISH) and single cell qRT-PCR (or single cell RNA-seq). While smFISH has been developed for culture cells, tissue sections and whole-mount invertebrate organisms, the method has not been reported for whole-mount vertebrate organisms. Here, we report an smFISH method that is suitable for whole-mount zebrafish embryo, a popular vertebrate model organism fScientific reports8571https://www.ebi.ac.uk/biostudies/studies/S-EPMC4339797biostudies-literatureWhole-mount single molecule FISH method for zebrafish embryo.PMC4339797Sato TNOka YfalseWhole-mount single molecule FISH method for zebrafish embryo.Noise in gene expression renders cells more adaptable to changing environment by imposing phenotypic and functional heterogeneity on genetically identical individual cells.
