Introduction
Spatial transcriptomics involves the use of Nanopore long-read sequencing technology to directly obtain data from Stereo-seq or 10X Visium HD 3', which provides spatially resolved information about full-length cDNA. By analyzing each spot, one can determine the results of isoform quantification and variable splicing events. It not only enables the identification of all RNA molecules but also retains the original positioning information within the tissue section. This is crucial for understanding the spatial distribution of gene expression, as the relationships within and between cells are significant.

Visium HD |
Ensure that fresh tissues are embedded in OCT within 30 minutes after ex vivo isolation. Length × Width: ≤ 6.5 mm × 6.5 mm; Height: ≥ 5 mm Mark the cut surface with an asterisk (*) or the label "Cut Surface". Stored at -80℃. |
Pack the sorted samples and embed them in dry ice and send it out as soon as possible. Ensure sufficient dry ice is used. |
|
Stereo-seq |
Ensure that fresh tissues are embedded in OCT within 30 minutes after ex vivo isolation. The maximum size of the tissue cut surface shall not exceed 0.9 times the chip size. The thickness of the embedded block shall be controlled within 2 cm. Mark the cut surface with an asterisk (*) or the label "Cut Surface". Stored at -80℃. |

Visium HD |
The recommended thickness of paraffin blocks is 2–5 mm. Length × Width: ≤ 6.5 mm × 6.5 mm; Height: ≥ 5 mm Mark the cut surface with an asterisk (*) or the label "Cut Surface". Store at room temperature or 4℃. |
Fix the samples in sample boxes to avoid squeezing the surfaces of paraffin blocks or glass slides, and transport them at 4℃ or room temperature. |
