Happy to see this published: Blind validation study of PancreaSeq GC across a prospective cohort of 1800+ patients but focused on 241 who underwent surgical resection. Look for our 10,000-patient study soon (along w/ WTS)! #PancreaticCyst #PancreaticCancer

FFPE Spatial ATAC-seq is finally possible — and now there’s a simple way to predict whether your tissue will succeed. FFPE blocks are some of the most valuable materials in translational research, but they’ve historically been difficult to use for spatial epigenomic assays. A
