Method Researchers calculated the volume in these different cellular compartments by imaging a cytoplasmicly expressed fluorescent protein and a fluorescent outer-membrane dye either simultaneously or individually.
Comments Based on researchers' measurements, the periplasm occupies approximately 16% of the total cell volume and the separation between the inner and outer membranes is (45±10) nm. For periplasmic volume of 30% see PMID 824274 p.334 left column top paragraph.
