The ratio of area under the curve (AUC0–t) between select tissues (blood, fat pad, heart, lung, pancreas, and stomach) and plasma. Ratio (y-axis) of accumulated AUC in tissues scaled to its corresponding accumulated AUC of plasma for solvent-based PTX (pac-T), nab-PTX (nab-P), mouse albumin nab-PTX (m-nab-P), micellar PTX (pac-P), and polymeric nanoparticle PTX (pac-G; Li, Zhang, Zhu, et al., 2018)
