MUC16 and non-small cell lung carcinoma: Further flow cytometry analysis of ch5E6 in PC (SW1990) and NSCLC (SW1573) cell lines suggested its specific binding to the cell surface bound MUC16 where 60–80% of the cells stained positive than negligible binding (5%) with human isotype control mAb huIgG1 (Fig. 2c).
