Table 1. Lipid formulations of the PEGylated DMPC liposomes used in this work. The amount of 32+ used for L123 and L23 varied; hence a concentration range is given here. The true ruthenium concentrations were determined with ICP-OES.
Sample | [DMPC] (mM) | [DSPE-PEG-2000] (μM) | [1] (μM) | [2] (μM) | [32+] (μM) |
L123 | 5.0 | 200 | 2.5 | 25 | 50–220 |
L12 | 5.0 | 200 | 2.5 | 25 | — |
L23 | 5.0 | 200 | — | 25 | 10–290 |
L2 | 5.0 | 200 | — | 25 | — |
L3 | 5.0 | 200 | — | — | 200 |
L0 | 5.0 | 200 | — | — | — |
