FR Expression in human OvCa tissue and cells. [A] Ovarian tissues were stained with anti-FRα antibody and DAB. FRα expression was highest in Stage IV OvCa tissues compared to matched normal tissues. [B] An Aperio ScanScope slide scanner system with a 40x objective was used to capture digital images of each tissue. [C] Immunoblot expression of the anti-FRα antibody in IOSE, OVCAR-3, CAOV-3, TOV-112D, and SW626 cells. β-Actin antibody was used as a loading control for all the samples
