The protein levels of genes were detected using western blot analysis. After the transfection for 48 h, the protein was extracted using RIPA buffer and separated on 10% sodium dodecyl sulfate–polyacrylamide gel electrolysis gel. Then, the protein was transferred into a PVDF membrane. After 1 h of the block with 5% non-fat milk, the membrane was incubated with primary antibodies at 4°C overnight and subsequently secondary antibodies at room temperature for 1 h. The primary antibodies anti-HIF1α (20960-1-AP) and anti-TRIM14 (15742-1-AP) were purchased from ProteinTech Group (Chicago, IL, United States). Protein bands were developed using an ECL kit (Solarbio Science and Technology Company, Beijing, China).

Quantifying Cell Signaling Proteins via Western Blot

Check if the same lab product or an alternative is used in the 5 most similar protocols
Antibodies were obtained from the following companies: anti-CNF1 (sc-52655, Santa Cruz Biotechnology, Santa Cruz, CA, USA), anti-LXRβ (ab28479, Abcam), anti-C/EBPα (8178, Cell Signaling Technology, Danvers, MA, USA), anti-HIF1α (20960-1-AP, Proteintech, Chicago, IL, USA), and anti-CD36 (18836-1-AP, Proteintech). Whole cell lysates were prepared using RIPA lysis buffer (Millipore, Billerica, MA, USA), adding complete protease inhibitors (Roche, Basel, Switzerland). The protein concentration was determined using the BCA Protein Assay Kit (ThermoFisher, Waltham, MA, USA). Approximately 30 μg of cell lysates were used for loading. Antibody binding was revealed using an HRPA conjugated anti-rabbit IgG (Sigma-Aldrich) or anti-mouse IgG (Sigma-Aldrich). Antibody complexes were detected using Immobilon Western Chemiluminescent HRP Substrate (Millipore) and exposure to Tanon-5200 machine.

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.
