Figure 2.
Flow cytometry assay of CEM (A, positive cells) and Ramos (B, negative cells) cells stained with anti-PTK7-PE and sgc8-FITC. FITC-labeled random DNA Library (Lib) and IgG-PE, which do not bind to cells, were used as negative control. A linear relationship was only shown on CEM cells stained with anti-PTK7-PE and sgc8-FITC (A, right).
