Figure 3From: Flow cytometric analysis of CK19 expression in the peripheral blood of breast carcinoma patients: relevance for circulating tumor cell detectionExpression of CK19 in A431 cells diluted with human white blood cells at different ratios. A431 cells were mixed with healthy adult white blood cells at different ratios of 1:1 (A), 1:10 (B), 1:102 (C), 1:103 (D), and 1:104 (E). The cell mixture was stained with FITC-anti-CK19 antibody and detected the expression of CK19.Back to article page
