Assessment of ESO expression in BC tumors from ESO Ab+ patients.ESO expression in cryopreserved BC tumors from ESO Ab+ patients was assessed by semi-quantitative PCR (A) and qPCR (B) using specific primers and ESO+ (SK-MEL-37, Me252) and ESO− (NA8, SK-MEL-23, Me290) tumor cell lines as internal controls.
