Western Blotting Technique for Protein Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Western blotting was carried out as described previously [24 (link)]. In brief, for Western blotting, proteins were extracted using RIPA buffer mixed with protease inhibitors (1:100), phenylmethylsulfonylfluoride (PMSF, 1:100) and dithiothreitol (DTT, 1:100) at 4 °C for 30 min. The lysate was centrifuged at 13000 rpm at 4 °C for 15 min. The supernatants were collected and protein concentrations were measured using the BCA method. For Western blot analysis, protein samples were separated by 8% SDS-PAGE and transferred onto polyvinylidene difluoride membranes (Bio-Rad). The membranes were then blocked with 5% nonfat milk and incubated with primary antibodies overnight followed by washing and reaction with horseradish peroxidase–conjugated secondary antibody for 1 h at 37 °C. The reaction was detected by using ECL reagents (GE Healthcare) and the signals were captured by X-ray films. Antibodies against RIF1 (sc-515,573) and β-actin (sc-58,673) were obtained from Santa Cruz Biotechnology. Antibodies against NANOG (ab21624) and SOX2 (ab97959) were purchased from Abcam.

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.
