Question: Can I place FFPE sections onto a Visium Spatial Gene Expression Slide during multiple sectioning sessions?
Answer: We would strongly advise placing sections within all Capture Areas on the Visium Slides during a single sectioning session. When we generated Spatial Gene Expression data from samples placed across multiple sectioning sessions, we found a decline in data quality generated from these samples. Therefore, customers should collect all their FFPE blocks and then section them in a single session.
