||EYFP-mit was targeted to the mitochondrial matrix by fusing it with a short peptide from
a mitochondria specific protein.
||Mitochondrial pH was found to be 7.98 ± 0.07 in HeLa cells and 7.91 ± 0.16 in cardiomyocytes (primary source 9). Using the same
method Porcelli et al. measured a pH of 7.78 ± 0.17 in ECV304 cells (human umbilical
vein endothelial cells, primary source 10).
