Ratios of total paclitaxel concentrations in select tissues (blood, fat pad, heart, lung, pancreas, stomach) scaled to corresponding plasma paclitaxel concentration at each time point for solvent-based paclitaxel (pac-T), nab-paclitaxel (nab-P), mouse albumin nab-paclitaxel (m-nab-P), micellar paclitaxel (pac-P), and polymeric nanoparticle paclitaxel (pac-G).
