  1. Relative binding percentage of PCS1 and PCS2 across 12 NSCLC lines and one normal bronchial epithelial line HBEC3KT. The right most column indicates the percentage of cells that are ALDH+ in an ALDH ALDEFLUOR assay. PCS1 and PCS2 have distinct binding patterns against 12 NSCLC lines, but do not correlate with previously published ALDH+ cell percentages (right most column). PCS1 and PCS2 did not bind to normal bronchial epithelial cells (HBEC3KT). Control compound shows no binding to any cell line. *Sullivan et al. Cancer Res. 2010 ND = No Data; PCS1 and PCS2 binding scores are: − = <1%; + = 2–10%; ++ = 11–20%; +++ = 20–30%; ++++ = 31–40%; +++++ = >40%.
