IHC detection of PD-L1 in seven patient tissues using fluorescent RK-10-cy5. Seven patient NSCLC tissues were stained using either SP263 or RKC-10-Cy5 peptide. All cases stained using RKC-10-Cy5 showed high affinity for tumor, while SP263 only showed heavy tumor staining in patient G and some lighter staining in patients C and D.
