Flow cytometric output for the EGFR and ErbB4 receptors screening in the other H-series cell lines. The polygonal R₁ boxes in A–F (cell lines are A H157, B H314, C H357, D H400, and E H413) represents the gating of the cells based on the forward and side scatter profiles to exclude cellular debris and doublet cells. A total of 10,000 gated events were acquired for analysis for each cell line. Similar analyses to obtain the true percentage of cells expressing EGFR and ErbB4 receptors were performed as per Figure 1.
