2D Western blot (1-color and 2-color):

1) Mouse liver samples were prepared using 2D lysis buffer.

2) Proteins was labeled and analyzed by 2D DIGE using pH 4-7 linear IPG strip according to Applied Biomics protocol. Left: DIGE with 1 CyDye labeling; Right: DIGE with 2 CyDye labeling

3) The images were scanned after 2D electrophoresis, using Typhoon 9400; then the proteins from 2D gel were transferred to membrane.

4) 1-color and 2-color Western blot:

Left: 1-color Western blot to reveal Keratin 8 (blue) and its posttranslational modified forms. The secondary antibody is CF488-labeled goat anti-mouse IgG (Biotium, Hayward, California).

Right: 2-color Western blot to reveal keratin 8 (red), Keratin 18 (green) and their posttranslational modified isoforms. The secondary antibodies are CF555-labeled goat anti-rabbit Ig and CF647-labeled goat anti-mouse Ig (Biotium, Hayward, California).

5) The 2D membrane was stripped after scanning, re-blocked, followed by Western blot to reveal beta-actin.
