VENTANA PD-L1 (SP142) IHC Assay

PD-L1 analytic assay | Step into the tumor microenvironment


PD-L1 diagnostic confidence

VENTANA PD-L1 (SP142) IHC Assay* is used to evaluate expression of PD-L1 protein in tumor cells and tumor infiltrating immune cells. PD-L1 expression may lead to inhibition of activated T cells and therefore, can indicate tumor immune evasion. This assay is highly specific, reproducible and designed to enhance visual contrast of immune cell staining within the tumor microenvironment. CE marked.

*Optimized for use on VENTANA BenchMark instruments.
