The rapidly advancing field of spatial biology has led to development of new platforms which provide measurements of gene and protein expression and their precise localization to defined tissue regions. The NanoStringGeoMxDSP (digital spatial profiling) platform enables spatial profiling using formalin-fixed, paraffin-embedded (FFPE) tumor biopsy samples with a read out using either the nCounteror next generation sequencing. In this study, IQVIA Laboratories evaluated both healthy tonsil sections and a well characterized breast carcinoma biopsy in a proof-of-concept study examining variability across days, patient biopsies and sample stability.
