Rabbit antiHuman CD274 antibody (AHP1703) used for the evaluation of PD-L1 expression on circulating tumor cells from cancer patients by immunofluorescence.
PD-L1 expression in CTCs isolated from prostate cancer, breast cancer, colon cancer, and osteosarcoma patients.
Cells were stained for CSV (green) using the 84-1 antibody, PD-L1 (red), and SYTOX green (pseudo blue). The images were taken using confocal microscopy. Scale bar, 10?μm.
