Question: Are fixed tissues embedded in OCT compatible with Xenium?
Answer: Fixed-frozen tissues are not tested for Xenium at this time. Unfortunately, we do not have guidance on tissue preparation for these samples. We recommend proceeding with either fresh frozen or FFPE tissue preparation, depending on the input sample. Additional information on supported tissue preparation methods can be found here: What fixation and embedding methods are compatible with Xenium using FFPE tissue inputs?
