Pharmacokinetic parameter estimates were derived from the data shown in Fig. 1
Non compartmental analysis was used to estimate area under the curve (AUC) from 0 to ∞ of gemcitabine and paclitaxel in DcNP and CrEL control
Apparent half-life was estimated from the slope of the last 3 time points collected in each condition
Concentration at time 0 was back extrapolated from the first time point in each condition
Dose/AUC is shown for the relative apparent clearances of gemcitabine and paclitaxel
Vss was calculated using Dose*AUMC/AUC2 extrapolated to infinity
Mean residence time (MRT) was calculated by dividing the area under the moment curve (AUMC) by the AUC from 0 to infinity
