PD-L1 expression on tumor versus antigen presenting cells investigated with multiplex IHC

Multiplexed IHC is a promising approach to profile cell types and map interactions to identify useful biomarkers. Staining with Ultivue’s UltiMapper™ I/O assays visualizes detailed information like the range of low to high expressing PD-L1 cells within tumor population, which provides a superior understanding of TME cell heterogeneity.
