Question: Can I use wide tissue slides (26 mm width) with the Visium CytAssist assay?
Answer: No, the Visium CytAssist assay is not compatible with 26 mm width tissue slides. Our Tissue Slide Cassettes (supplied in Visium CytAssist Spatial Gene Expression kits) currently support glass slides with the maximum dimensions specified in Table 1 below.
|Length (mm)||Width (mm)||Thickness (mm)|
|Table 1. Minimum and maximum length, width, and thickness of glass slides the Visium CytAssist Tissue Slide Cassette supports.|
Listed in Table 2 are specific brands of glass slides that have been identified to not fit Visium CytAssist Tissue Slide Cassettes. Use of these slides is strongly discouraged as they may impact assay performance due to slide breakage and/or cassette leakage.
|Slide Brand||Slide Name||
|Muto-Kagaku||Star Frost Glass|
|Trajan||Series 2 Adhesive|
