The 10x Genomics Xenium Spatial Analyzer is an advanced spatial biology platform that measures the expression and precise subcellular location of hundreds to thousands of RNA targets directly within intact tissue sections. Using probe-based detection, rolling circle amplification, and cyclical high-throughput imaging, Xenium generates highly resolved spatial transcriptomic maps that preserve tissue architecture and cellular context. This enables detailed analysis of cell types, states, and interactions, supporting deep biological insights in research areas such as cancer, immunology, and tissue biology. Ready-to-use or custom panels are available for greater flexibility.
