Cells were harvested and lysed with protease inhibitor-containing EBC buffer (50 mM Tris pH 8.0, 120 mM NaCl, 0.5% NP-40). After lysing, cells were centrifuged at 4 °C. The resulting supernatant was removed prior to quantification of protein concentration using Bradford Assay. Laemmli buffer and β-Mercaptoethanol was added to equal amounts of protein in cell lysates. Protein samples of 100 – 200 μg were subsequently separated with 12% and 8% Sodium Dodecyl Sulfate polyacrylamide gel electrophoresis before transfer to PVDF membrane (Bio-Rad). Primary antibodies were added overnight following blocking in 5% milk in PBS-T, and were as follows: rabbit His-tag antibody (Cell Signalling Technology, RRID:AB_2115720), mouse CHD antibody (Santa Cruz Biotechnology, RRID:AB_10610044), mouse monoclonal p16INK4a antibody (BD Pharmingen, RRID:AB_394077), mouse monoclonal β-actin (Santa Cruz Biotechnology, RRID:AB_2833259), mouse FLAG-tag antibody (Sigma-Aldrich) and rabbit cleaved caspase-3 (CC3) antibody (Cell Signalling Technology).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
