Question: How do I practice sectioning and tissue placement for Visium for FFPE v1?
Answer: Sectioning and placement can be practiced using a control FFPE block and plain glass slides with dimensions (75 x 25 x 1 mm) similar to Visium slides. Using a water-proof marker, draw 6.5 x 6.5 mm squares on the back of regular slides using the layout in the Tissue Preparation Guide as a template. The squares are representative of the Capture Areas. Then, place sections of the control block in the squares by following the guidance in the Visium for FFPE Tissue Preparation Guide.
Please note: the following biobanks have FFPE tissue available for purchase if control blocks are needed: BioIVT, Avaden Bio, Precision For Medicine, and BioChain.
