MULTIPLEX ASSAY FOR IMPROVED SCORING OF TUMOR TISSUES STAINED FOR PD-L1

摘要

Multiplex assays for improved scoring of tumor tissues stained with PD-L1 featuring PD-L1 staining in a first color plus staining of one or more differentiating markers, such as a marker specific for tumor cells and a marker specific for immune cells, are disclosed. The differentiation between the tumor cells and immune cells may improve the ease of scoring, the accuracy and speed of scoring, and the reproducibility of scoring of PD-L1 positive samples for therapy purposes.
