a, Cultured TRPML1-/- (ML1-/-) skin fibroblasts showed less de-quenching of the iron-sensitive fluorescence than ML1+/- cells did. De-quenching was achieved by preloading the fibroblasts with an iron-sensitive dye, Phen Green SK (PG SK), and then adding the membrane-permeable transition metal chelator, 2,2′-bipyridyl (BPD). 2,2′-BPD is predicted to chelate free cellular iron (also referred to as chelatable or labile iron), which subsequently increases PG SK fluorescence. The original magnification used was ×200
