amphiphile | length (nm)a | radius (nm)a | apparent aspect ratio (L/R)b |
---|---|---|---|
A40-(FGG)8 | 56.6 ± 26.0 | 6.5 ± 1.5 | 8.7 ± 1.1 |
A80-(FGG)8 | 63.5 ± 25.4 | 6.5 ± 1.5 | 9.8 ± 1.1 |
A160-(FGG)8 | 110.2 ± 34.0 | 10.0 ± 1.7 | 11.0 ± 1.1 |
A160-(YG)8 | 118.6 ± 32.5 | 11.8 ± 1.9 | 10.1 ± 3.2 |
A160-Y8 | 59.7 ± 11.3 | 11.3 ± 3.5 | 5.3 ± 0.6 |
Data are reported as mean ± standard deviation with a minimum of 25 measurements.
This apparent aspect ratio is defined only by the portion of the assembly that is visible by cryo-TEM and as such differs from the true aspect ratio determined by scattering.
