Bragg peaks with miller indices are shown in Fig. A, B and C corresponding to phytantriol (blue), monoolein (grey) and phytantriol/tocopherol acetate (yellow). Linear regression plots are given in Fig. D. The intercept of the regression line for phytantriol and monoolein cubosomes was very near zero, signifying correct phase assignment. A table in Fig. E compares a and dhk(l) values obtained via SAXS with those estimated by cryo-EM. All values were in excellent agreement with one another.
