Total protein was extracted from tissues by RIPA lysis buffer (Beyotime), 10 μL PMSF and 10 μL phosphatase inhibitor. SDS-PAGE gel electrophoresis was utilized to separate the extracted protein. The protein was transferred to polyvinylidene fluoride membrane. After blocking with 50 g/L BAS for 1 h, the membrane was incubated with primary antibodies against HTR2B (1/3000; ab227722; Abcam, Cambridge, MA, United States), SLC5A3 (1/1000; ab113245), GAPDH (1/3000; ab8245), TNF-α (1/1000; ab215188), IL-1β (1/1000; ab200478), TGF-β (9ab208156) and IL-4 (1/1000; ab34277) at 4°C overnight. After washing the membrane with TBST, the membrane was incubated with secondary antibody (1/5000; ab7097) for 1.5 h. The ultra-sensitive ECL chemiluminescence kit was used to configure the luminescence buffer, and the band was developed.

After removing the culture medium, 500 μl protein lysate is added to each well for lysis for 30 minutes, centrifuged at 4° C, 1500 r/min for 5 minutes. And the supernatant is taken to detect the protein concentration AGING of the sample. Transfer the protein to PVDF membrane through Gels preparation, samples loading, electrophoresis and wet transfer and close the blocking solution for 1 hour. Sequentially, primary antibody SHP2 (Abcam, ab187040, 1:5000), Ki-67 (Abcam, ab231172, 1:5000), p-STAT1 (Abcam, ab109461, 1:1000), p-STAT3 (Abcam, ab76315, 1:1000), p-STAT5 (Abcam, ab278764, 1:1000), p-STAT6 (Abcam, ab263947, 1:1000), IL-4 (Abcam, ab34277, 1:1000), IL-10 (Abcam, ab52909, 1:1000), Cathepsin-L (Abcam, ab200738, 1:1000), Cathepsin-S (Abcam, ab134157, 1:1000), Cathepsin-K (Abcam, ab207086, 1:1000), Arginase-1 (Abcam, ab133543, 1:1000) and GAPDH (Abcam, ab181603, 1:10000) are added and the secondary antibody is incubated for 2 hours at room temperature. Exposure imaging is performed and Quantity One V4 software is used for analysis.

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.
