Validation of MPI. Subcellular distribution (A) and MPIs (B) of a series of hSOD-FP fusions. Mito, mix, and cyto denote fractions of cells with purely mitochondrial, mixed mitochondrial and cytoplasmic, and purely cytoplasmic localization of FP, respectively. Note that MPI faithfully recapitulates the trend in subcellular distribution of FP
