Cells were washed in PBS and lysed in the following buffer: 50 mM Tris–HCl, pH 7.4, 0.5%
IGEPAL (Sigma‐Aldrich, St. Louis, MO, USA), 150 mM NaCl, 1 mM DTT, 5% glycerol, 50 mM NaF, 1 mM PMSF, 25 mM β‐glycerophosphate, 1 mM vanadate,
Complete Mini Protease Inhibitor Cocktail (Roche Diagnostics, Basel, Switzerland). Proteins were then resolved by SDS–PAGE and transferred onto a nitrocellulose membrane. Primary antibodies were directed against
α‐tubulin (clone DM1A, 1:5,000; Sigma‐Aldrich, St. Louis, MO, USA),
γ‐tubulin (clone GTU‐88, 1:5,000; Sigma‐Aldrich, St. Louis, MO, USA), GFP (
ab290; 1:5,000; Abcam, Cambridge, UK), STIL (
ab89314, 1:2,000; Abcam, Cambridge, UK), Sas‐6 (Kleylein‐Sohn
et al,
2007), CP110 (1:2,000, Schmidt
et al,
2009), cyclin A (1:2,000, Maridor
et al,
1993),
cyclin B1 (05‐373, 1:2,000, Merck Millipore, Darmstadt, Germany), and
phospho‐histone H3/serine 10 (3377, 1:1,000, Cell Signaling Technology, Danvers, MA, USA); secondary antibodies were
HRP‐conjugated anti‐mouse immunoglobulin (170‐6516, 1:3,000, Bio‐Rad, Hercules, CA, USA) or
anti‐rabbit immunoglobulin (170‐6515, 1:3,000, Bio‐Rad, Hercules, CA, USA).
