VENTANA PD-L1 (SP142) assay is an FDA approved IVD assay using rabbit monoclonal anti-PD-L1 clone SP142 intended for assessment of the PD-L1 protein in urothelial carcinoma tissue. PD-L1 status is determined by the proportion of tumor area occupied by PD-L1 expressing tumor-infiltrating immune cells (%IC) of any intensity. PD-L1 expression in ≥ 5% IC determined by VENTANA PD-L1 (SP142) assay in urothelial carcinoma tissue is associated with increased objective response rate (ORR) in a non-randomized study of Atezolizumab. Subcellular Localization: Membranous (on immune cells)
Organ: Genitourinary Tumors
