Western blotting was carried out as described23 (link). Phos-tag SDS–polyacrylamide gel electrophoresis gels were made from 7% acrylamide (37.5:1 crosslinking ratio), 70 μM Phos-tag reagent (Wako Pure Chemical Industries) and 140 μM MnCl₂, and were processed according to the manufacturer’s manual. Proteins were detected using the following primary antibodies: mouse anti-GFP (1:1,000, Roche 11814460001), mouse anti-PLK1 (1:2,000, Santa Cruz sc-17783), mouse anti-histone H3 pSer10 (1:5000, Abcam 14955), mouse anti-α-tubulin (1:5000, Sigma-Aldrich T9026), rabbit anti-phospho-(Ser) CDK substrate (1:1000, Cell Signaling 2324), rabbit anti-histone H3 (1:2000, Abcam ab1791), mouse anti-FLAG HRP (1:1,000, Sigma-Aldrich A8592), mouse anti-MUS81 (1:1,000, Santa Cruz sc-47692), mouse anti-BLM (1:500, Santa Cruz sc-70426), rabbit anti-KAP-1 pSer842 (1:1000, Abcam ab70369), rabbit anti-CHK1 pSer345 (1:1000, Cell Signaling 2341), mouse anti-histone H2A.X pSer139 (1:1000, Millipore 05-636-1), rabbit anti-GEN1 (1:100, raised against GEN1^890–908)19 (link). Uncropped blots are shown in Supplementary Fig. 5.

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.
