Select cases from NSCLC TMA stained with fluorescent RK-10-Cy5 or SP263. Six of 192 cores from Biomax TMA LC1923 are shown which were stained using either Roche SP263 antibody (top) or RKC-10-Cy5 peptide (bottom). Shown are representative samples which show negative PD-L1 with both methods (a), positive PD-L1 with both methods (b,c), and samples which are negative using SP263 but stain positive in the tumor using RKC-10-Cy5.
