by detecting the caspase-cleaved cytokeratin 18 (M30
antigen). It shows that M30 antigen increases in A549
non-small cell lung cancer cell line by treatment with
cisplatin (10 μM) and paclitaxel (7 μM) for 48 hours.
CHO (Chinese Hamster Ovary) cell line is used for the
negative control in which there is no cytokeratin 18 that
is detectable by the M30 antigen ELISA assay in this cell
line.
