STOmics Stereo-seq Transcriptomics Set for Chip-on-a-slide enables a “tissue-to-data” solution through in situ capture of the whole transcriptome, at nanoscale resolution and centimeter-sized field of view. Stereo-seq Transcriptomics Solution utilizes DNB patterned array chips loaded with spatially-barcoded probes that capture and prime poly-adenylated mRNA from tissue sections in situ. Each cDNA synthesized from mRNA captured on a particular spot is linked to its spatially-barcoded probe, allowing subsequent gene expression mapping of a tissue section following sequencing and visualization analysis using the StereoMap visualization platform.
