We have explored the question of whether the renormalization group running of the neutrino mixing parameters in the Minimal Supersymmetric Standard Model is detectable with ultra-high energy neutrinos from active galactic nuclei (AGN). We use as observables the ratios of neutrino fluxes produced at the AGN, focusing on four different neutrino production models: $(\Phi_{\nu_e+\bar{\nu}_e}^0 : \Phi_{\nu_\mu+\bar{\nu}_\mu}^0 : \Phi_{\nu_\tau+\bar{\nu}_\tau}^0)$ = (1:2:0), (0:1:0), (1:0:0), and (1:1:0). The prospects for observing deviations experimentally are taken into consideration, and we find out that it is necessary to impose a cut-off on the transferred momentum of $Q^2 \geq 10^7$ GeV$^2$. However, this condition, together with the expected low value of the diffuse AGN neutrino flux, yields a negligible event rate at a km-scale Cherenkov detector such as IceCube.
