Formulation of a tocopherol-based vehicle for antigen delivery. A.) Emulsion fabrication using varied proportions of Vitamin E, TPGS and PBS enabled the construction of a ternary phase diagram, where scale denotes percent composition of each component. B.) Favorable component proportions were used to fabricate emulsions both with (ETPGS+PLP) and without (ETPGS) PLP for sizing via dynamic light scattering (n = 3/group) DLS sizes and half-widths are presented in terms of average size ± standard deviation. C.) formulations of ETPGS alone (left) and ETPGS+PLP (right) were also imaged with TEM to verify antigen incorporation into the emulsion. The lower right scale bar represents 500 nm for both formulations.
