Tryptophan anisotropy changes upon SUV interaction

The mean (n = 303) and standard deviations are represented. The t test showed no statistical significance between Trp-82 in solution versus the presence of DOPC SUVs (p = 0.344). Likewise, PimA Trp-154 t test showed no statistical significance between Trp-154 in solution versus the presence of DOPC SUVs (p = 0.3051). Nevertheless, PimA Trp-349 values revealed significant differences between in solution versus DOPC and/or DOPC/DOPG. However, the values obtained in the presence of PI-containing liposomes were not statistically significant (n = 303; p = 0.0589).
