Proteins from cells were extracted using radioimmunoprecipitation assay (RIPA) lysis buffer (CWBIO, China) with protease and phosphatase inhibitors (CWBIO, China). Identical quantities of proteins were electrophoresed by SDS-PAGE, transferred onto PVDF membranes, blocked with 5% non-fat milk for 1 h, and incubated with primary antibodies specific for Bax, Bcl-2, Caspase-3 (#2772, #2872, and #9662) (1 : 1000, Cell Signaling Technology, USA), and β-actin (66009-1-Ig, 1 : 5000, Proteintech, USA) at 4°C overnight, followed by incubation with anti-rabbit/mouse HRP-conjugated secondary antibodies (cw0103s, cw0102s) (1 : 2000, CWBIO, China) at room temperature for 1 h. Signals were detected by Immobilon ECL substrate (Millipore, Germany).

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.
