Webb7 apr. 2024 · In contrast to sequential imaging of barcoded FISH probes, in situ sequencing (ISS) is an alternative approach for identifying a larger number of RNA-targeting probes by direct imaging of nucleotide sequences in situ (Figure 1d–f). In principle, both FISH and ISS provide similar transcriptome information at subcellular resolution.
