Fig. 7. Comparison of filaments formed by endogenous LIII (`endo LIII'), overexpressed LIII, lamin B2 and lamin A, and short filaments of lamin A obtained at low levels of expression (`short A'; inset). All filaments are shown at the same magnification. The chart shows the mean diameter, including the chromium coat, with standard deviation bars for each filament type (n>100).
