Figure 2From: NMR studies of the relationship between the changes of membrane lipids and the cisplatin-resistance of A549/DDP cells1H-NMR spectra of A549 cells (A) and A549/DDP cells (B) treated with a clinical dose of 30 μM cisplatin and cultured for 0 h, 24 h, and 48 h. The cell concentrations are comparable (1 × 107 cells/mL) for each sample. The peak assignments are shown in the figures. Number of scans was 128.Back to article page
