Figure 2.
Body weight of mice intramuscularly inoculated with the same dose (600 µg) of 250, 450, 750, or 850 nm zein particles at weeks 0, 1, and 3. The control group followed the same inoculation scheme using the same volume of solvent instead of zein particles. All p-value calculations are based on the t-test of the two-sample equal variance hypothesis. *p < 0.05 compared to control.
