Whole-cell lysates of liver tissue or cells were obtained using RIPA lysis buffer containing protease and phosphatase inhibitors. Protein samples were separated by 5% or 10% SDS-PAGE. Then, the proteins were transferred onto a polyvinylidene fluoride membrane and incubated with primary antibodies at 4 °C overnight. Corresponding secondary antibodies were applied to the membrane and incubated for 1 h. Protein bands were visualized by chemiluminescence. The following primary antibodies were used: JNK (sc-571; Santa Cruz Biotechnology), P-JNK (sc-6254; Santa Cruz Biotechnology), TGF-β1 (ab106582, Abcam), αSMA (sc-53142; Santa Cruz Biotechnology), and β-actin (sc-47778, Santa Cruz Biotechnology).

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.
