a
Short axis of the fibrillar cross section.
b
Aspect ratio between the short and long axis of the ellipsoidal cross section.
c
Scale factor of experimental data of 10 mM pure LPG/LPC (Fig. 4D).
d
Diameter of a single filament on a TEM image obtained by measuring 75 to 178 single filaments for each sample and fitting this with a Gaussian distribution to obtain the maximum and uncertainty (individual distributions in Fig. S8).
