Western Blot Analysis of S100A9

Check if the same lab product or an alternative is used in the 5 most similar protocols
After mixing with 5 × SDS-loading buffer and denaturation at 95 °C, prepared samples were loaded onto and separated by 8–12% SDS polyacrylamide gel electrophoresis. Thereafter, the gels were transferred onto a polyvinylidene fluoride membranes, followed by blocking using 10% evaporated milk. Membranes were incubated with rabbit anti-S100A9 antibody (1:1000; Abcam, ab242945) and anti-rabbit HRP-conjugated secondary antibody. β-actin was served as a loading control. The blots were visualized under electrochemiluminescence system.

Western Blot Analysis of Liver Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
The liver tissues were removed and fully lysed using a RIPA lysis buffer. The homogenates were centrifuged at 13,300 rpm at 4 °C for 15 min. The protein concentrations in the supernatant were quantified by the BCA method (Thermo Fisher, Carlsbad, CA, USA). A total of 50 μg of protein per sample was resolved by 7.5–15% SDS–PAGE and transferred onto a PVDF membrane. Next, the membranes were blocked in 5% skim milk for 1 h at room temperature and incubated with the appropriate primary antibodies at 4 °C overnight, and then incubated with the secondary antibodies at room temperature for 1 h. Finally, the membranes were developed on a FluorChem M System (PerkinElmer, Waltham, MA, USA). The intensities of protein bands were quantified with NIH Image J version 1.48, and the relative levels of the corresponding proteins were calculated in each group. The primary antibody against S100A9 (ab242945, 1:1000) was from Abcam (Cambridge, MA, USA). Antibodies against S100A8 (47310; 1:1000), p-AMPK (2535; 1:1000), AMPK (5831; 1:1000), p-AKT (4060; 1:2000), AKT (4691; 1:1000), ACC (3662; 1:1000) and β-actin (4970; 1:1000) were from Cell Signaling Technology (CST, Danvers, MA, USA). Antibodies against GLUT4 (66846-1-Ig; 1:3000), Bax (50399-2-Ig; 1:7000) and Bcl-2 (12789-1-AP; 1:2000) were obtained from Proteintech Group (Chicago, IL, USA).

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.
