10X Visium - Mouse Embryo
Gene expression library of Mouse Embryo (CytAssist FFPE) using the Mouse Whole Transcriptome Probe Set
Description
The tissue was sectioned as described in Visium CytAssist Spatial Gene Expression for FFPE Tissue Preparation Guide Demonstrated Protocol CG000518. Tissue sections of 5 µm was placed on a standard glass slide, and H&E-stained following deparaffinization. Sections were coverslipped with 85% glycerol, imaged, decoverslipped, followed by dehydration & decrosslinking (Demonstrated Protocol CG000520). The glass slide with the tissue section was processed with the Visium CytAssist instrument to transfer analytes to a Visium CytAssist Spatial Gene Expression slide (11 mm Capture Area). The probe extension and library construction steps follow the standard Visium for FFPE workflow outside of the instrument.
