Method Primary source abstract: "The antibody-labelling technique (Asakura et al., 1968) made it possible to show that, though active filaments having equal lengths grew at various rates ranging between 0 and 0.16 μm/min, the average value of growth rate depended little on length."
Comments P.6042 left column 2nd paragraph: "The final length of the cannulae [a network of tubules in which archaeal cells grow] varied between 30 and 150 μm with an elongation rate of 1.0 to 1.5 μm/min, which is significantly higher than the elongation rate for bacterial flagella, e.g., Salmonella (0.16 μm/min in in vitro measurements) (primary source)."
