Rule of thumb for time it takes protein to diffuse across HeLa cell

Value 10 sec
Organism Human Homo sapiens
Reference Calculated according to HeLa cell diameter. Please see Measurement Method
Method Taking X, distance to be traveled, as 21µm (BNID 103 788) and D of protein as 10µm^2/sec (5-15 µm^2/sec BNID 100 193, 100198). According to equation of diffusion (in 3 dimensions): t diffusion=X^2/(6×D). (21µm)^2/(60µm^2/sec)=7.35sec≈10sec.
Comments For time it takes a protein to diffuse across an E. coli cell see BNID 103 801.
