FIG. 5.

Lamin A/C and B1 expression in cell nuclear fractions. (a) Western blot (upper panel) and band density (lower panel) quantifying nuclear envelope protein lamin A/C expression and β-actin loading control. Lamin band densities are normalized by β-actin loading control band densities. (b) Western blot (upper panel) and band density (lower panel) of lamin B1 and β-actin expression. (c) The ratio of lamin A/C and lamin B1 expression, obtained from the density graphs in (a) and (b). Four independent samples were used for all blot quantifications.
