The uptake of the 14C-chelators was examined in a variety of immortal cancer/transformed cell-types (i.e., SK-N-MC neuroepithelioma, SK-Mel-28 melanoma, MCF-7 breast cancer, DMS-53 lung carcinoma, HepG2 hepatoma, HK-2 immortalized kidney proximal tubule epithelial cells) and normal, mortal cells (i.e., HUVECs and MRC-5 fibroblasts) in HSA-containing (40 mg/mL) or protein-free media for 2 h/37°C (Supplementary Fig. 2A-C). Here, ALB is linked to breast cancer.
