Abstract
In situ hybridization based on the mechanism of hybridization chain reaction (HCR) enables multiplexed quantitative mRNA imaging in the anatomical context of whole-mount vertebrate embryos. Third-generation in situ HCR (v3.0) provides automatic background suppression throughout the protocol, dramatically enhancing performance and ease of use. In situ HCR v3.0 supports two quantitative imaging modes: (1) qHCR imaging for analog mRNA relative quantitation with subcellular resolution in an anatomical context and (2) dHCR imaging for digital mRNA absolute quantitation with single-molecule resolution in an anatomical context. Here, we provide protocols for qHCR and dHCR imaging in whole-mount zebrafish, chicken, and mouse embryos.
