EPLC-272H and H1339 lung cancer cell lines show similar drug-sensitivity.
EPLC-272H and H1339 cells were exposed to vehicle control (0 nM), 17-AAG (5–50 nM) or NVP-AUY922 (1–3.75 nM). Drugs were present until fixation of colonies. The survival fraction was calculated relative to the untreated control. Horizontal lines indicate 50% survival fraction. Mean values ± SEM of at least 4 independent experiments are shown.
