Triple-immunofluorescence (CK/Twist/CD45, CK/vimentin/CD45) in CTCs. Representative ARIOL system photomicrographs of CTC cytospin after negative immunomagnetic separation in patients with metastatic breast cancer. (A) Cells were triple-stained with pan-CK A45-B/B3 antibody/Zenon Alexa Fluor 488 (green)/Twist anti-rabbit antibody/Alexa Fluor 555 anti-rabbit antibody (orange) and CD45 anti-mouse/Alexa Fluor 633 anti-mouse antibody (blue). Original magnification, x400. (B) Cells were triple-stained with pan-CK A45-B/B3 antibody/Zenon-Alexa Fluor 488 (green)/vimentin anti-rabbit antibody/Alexa Fluor 555 anti-rabbit antibody (orange) and CD45 anti-mouse/Alexa Fluor 633 anti-mouse antibody (blue). Original magnification, x400. ARIOL system = automated image analysis system; CK = cytokeratin; CTCs = circulating tumour cells.
