Table 3.

Physical characteristics of murabutide (MB)-loaded, ovalbumin (OVA)-loaded, and empty (EMPs) acetalated dextran (Ace-DEX) microparticles (MPs) of different cyclic acetal coverage (CAC). EE stands for encapsulation efficiency. Mean diameter was measured through dynamic light scattering as number-weighted average. Data are presented as mean ± standard deviation (n = 5).
