Question: Can I section from the same FFPE tissue block across multiple days?
Answer: The same tissue block can be taken in and out of storage at 4°C for sectioning on multiple days. This allows you to collect sections for RNA Quality Assessment (DV200% determination) one day and on another day, section tissues from the same tissue block for Gene Expression Slide placement. Ensure to discard the first few sections before collecting sections for placement on the Gene Expression Slides if the block is already faced.
Please note: tissue placement onto Visium Slides should all be performed during the same sectioning sitting and not extended across multiple days.
