||The simplest and most convenient method to
measure organellar pH is through the targeted
delivery of pH-sensitive spectroscopic probes.
||This is average of range, 6.0 to 6.7. "...the cis Golgi network is slightly acidic with a pH of approximately
6.7. There is a gradual drop in pH inside the Golgi apparatus moving towards the trans face and in the trans Golgi
network the pH is around 6.0." (quote from PMID 22768925)
