Western Blot Analysis of Liver Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Liver tissues were homogenized with a lysis buffer containing RIPA and phosphatase-inhibitors on ice. Protein concentration was quantificated by BCA kit (ThermoFisher Scientific) after centrifuged at 13,000 r/min at 4℃ for 15 min. Thirty microgram proteins were subjected to 10% SDS-PAGE electrophoresis and transferred to polyvinylidene difluoride (PVDF) membrane. Membranes were blocked with 3% BSA for 2 h and then immunoblotted with primary antibodies (Nrf2, 12721; Keap1, 8047; p62, 5114; p-p62, 95697; β-actin, 4970; Cell Signaling Technology, Danvers, MA) diluted with 3% BSA for 2 h at room temperature. The membranes were incubated with secondary antibodies (Anti-rabbit IgG, 7074; Cell Signaling Technology, Danvers, MA), followed by visualized with the Chemiluminescence System. And the gray level of the protein expression was analyzed by using the software, ImageJ.

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.
