Method The simplest and most convenient method to measure organellar pH is through the targeted delivery of pH-sensitive spectroscopic probes.
Comments "A pH gradient in the opposite direction has been observed in the endocytic pathway towards the lysosomes. While early endosomes are thought to have a pH of around 6.3, lysosomes are much more acidic with a pH of approximately 5.5." (quote from PMID 22768925)
