Total cell extracts were resolved by SDS-PAGE in the presence of 15 µM PhosTag (upper panel), or conventional SDS-PAGE (middle panel), and Cdc12 levels were detected by incubation with anti-HA HRP-conjugated antibody. Anti-Cdc2 (lower panel) was used as a loading control. Representative experiments are shown.
