Diffusion constant of lipopolysaccharide (LPS) in the outer membrane

Value 0.02 μm^2/sec Range: ±0.009 μm^2/sec
Organism Bacteria Salmonella typhimurium
Reference Schindler M, Osborn MJ, Koppel DE. Lateral diffusion of lipopolysaccharide in the outer membrane of Salmonella typhimurium. Nature. 1980 May 22 285(5762):261-3. abstractPubMed ID6990276
Method FRAP procedure (fluorescence redistribution after photobleaching)
Comments "The method used extends the FRAP procedure (fluorescence redistribution after photobleaching) to bacteria and the results demonstrate rapid diffusion of lipopolysaccharide (D = 2.0±0.9x10^-10cm^2/sec) over micrometre distances." See BNID 110087
