Panc02 cells (N = 2000) were plated into each well of 6-well plates. Old media were removed and fresh media were applied after 2 days. After 4 days, the cells were stained and fixed with methylene blue (10 mg/ml) in 50% methanol for 10 min and rinsed with distilled water. The plates were scanned and colony intensity % and area % were quantified using ImageJ software.
