PDLSCs were lysed with NP-40 (Beyotime, Nantong, China) on ice for 10 min, and the supernatant was collected after centrifugation. The supernatant samples were incubated with the primary antibodies (2.5 μg) and Protein A/G Plus Agarose (sc-2003, Santa) at 4°C overnight. And the primary antibodies used in this study for enriching the protein complex were presented below: Nrf2 (16396-1-AP, Proteintech), Akt (10176-2-AP, Proteintech), HO1 (10701-1-AP, Proteintech), SOD2 (24127-1-AP, Proteintech). After immunoprecipitation, the immunocomplexes were washed three times with NP-40 lysis buffer, collected after centrifugation, and then re-suspended with SDS-loading buffer, and boiled for 5 min for western blotting. The primary antibodies used for western blotting were presented below: Nrf2 (66504-1-lg, Proteintech), Akt (60203-2-lg, Proteintech), HO1 (66743-1-lg, Proteintech), SOD2 (66474-1-lg, Proteintech).

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.
