Method P.2926 right column bottom paragraph: "From the contrast of the tubules in the DIC [Differential Interference Contrast microscopy] images it was possible to estimate the relative diameters (Fig. 4)."
Comments P.2926 right column bottom paragraph: "Golgi tubules had an average diameter of ∼180 nm whereas the ER network branches were ∼115 nm in diameter or a factor of RG/RE= 1.57 ± 0.2 (Fig. 4). The inverse ratio of tether forces is FE/FG = 1.63 ± 0.3 [See values in range of BNID 112516]. [Investigators] find that the two ratios (FE/FG and RG/RE) are the same within experimental error. "
