PBPK model predicted vs. observed plasma PK profiles of different-size proteins. The solid lines represent model
predictions, and solid symbols represent pool observed data from one or more studies. The dataset include: nanobody (13 kDa, n=3),
scFv (27 kDa, n=13), diabody (50kDa, n=2), Fab (50kDa, n=6), scFv2 (55 kDa, n=2), minibody (80 kDa, n=3),
F(ab)2 (100 kDa, n=6), scFv-Fc (105 kDa, n=2), and IgG in FcRn KO mice (150 kDa, n=1).
