Tissue lysate was obtained by the total protein extraction kit (Solarbio, Beijing, China). After protein samples transferring to PVDF membranes, we cut off the extra PVDF membrane according to the molecular weight of the target protein. Then, the remaining PVDF membrane was incubated with a primary antibody. Antibodies were diluted 1:500 for rabbit anti-UCP1 (Cat: 72,298; Cell Signaling Technology, MA, USA), 1:500 for rabbit anti-PGC1α (Cat: A12348; ABclonal, Wuhan, China), 1:1000 for rabbit anti-β-Tubulin (Cat: AC008; Abclonal, Wuhan, China), and 1:1000 for HPR-labeled goat anti-rabbit IgG (Beyotime, Shanghai, China). Finally, a ChemiDoc Imaging Systems (Bio-Rad, CA, USA) was used to detect immunoreactive proteins.

Protein extraction and Western blotting were performed as described in [32 (link)] by applying the following primary antibodies: mouse anti-actin (MAB1501, 1:10,000, Merck Millipore); rabbit anti-Fhl2 (provided by the Schüle Laboratory, University of Freiburg, Freiburg im Breisgau, Germany); rabbit anti-GAPDH (#2118, 1:1000, Cell Signaling); mouse anti-MCP-1 (MA5-17040, 1:1000, Invitrogen); and rabbit anti-UCP1 (#14640, 1:1000, Cell Signaling). Mouse anti-rabbit (sc-2357, 1:10,000, Santa Cruz Biotechnology, Dallas, TX, USA) and horse anti-mouse (#7076, 1:3000, Cell Signaling) were used as secondary antibodies.
For the quantification of NPY and MCP-1 in tissue and cell protein lysates or supernatants, commercially available mouse NPY (Merck, Darmstadt, Germany) and CCL2/MCP-1 (R&D Systems, Minneapolis, MN, USA) ELISA kits were used according to the manufacturer’s instructions.

We conducted immunocytochemistry analysis on brown and white adipocytes. The adipocytes were initially fixed with 4% paraformaldehyde for 15 min and subsequently incubated with 0.25% Triton X-100 (Solarbio, Beijing, China) at room temperature for 10 min. Subsequently, the washed cells were incubated overnight at 4 °C with the following primary antibodies: rabbit anti-UCP1 (dilution 1:100, Cell Signaling Technologies, Danvers, MA, USA) and rabbit anti-FGF11 (dilution 1:250, Bioss, Beijing, China). The cells were incubated with the secondary antibody (Cy3 Goat Anti-Rabbit IgG) diluted at 1:500 and maintained at 37 °C for 1 h. Finally, the cells were stained with DAPI and observed under a microscope.

The adipose tissues were lysed in RIPA buffer containing 0.5% NP-40, 0.1% sodium deoxycholate, 150 mM NaCl, 50 mM Tris-Cl, pH 7.5, protease inhibitor cocktail (Complete, Roche), and 1 mM phenylmethylsulfonyl fluoride. Protein concentrations were quantified using a detergent-compatible protein assay kit (Bio-Rad). Lysates were run on Bis-Tris gels, transferred to a PVDF membrane (Millipore), and probed with primary antibodies. The following antibodies were used: rabbit anti-UCP1 (Cell Signaling, 72298), mouse anti-Actin (Millipore, MAB1501), and mouse anti-PGC1α (Sigma, ABE868). Goat-anti-rabbit IgG conjugated to horseradish peroxidase (Cell Signaling Technology) was used as the secondary antibody.

The proteins used in the experiments were extracted using the protein extraction kit (Bestbio, Shanghai, China). The following primary antibodies were used: dilution 1:1000 for rabbit anti-UCP1 (Cell Signaling Technologies, MA, USA), and dilution 1:3000 for rabbit anti-β-Tubulin (Abclonal, Wuhan, China). The primary antibodies were incubated at 4 °C overnight. HRP-labeled goat anti-rabbit secondary antibody was diluted at 1:1000 for 1.5 h at 37 °C. Finally, the proteins were detected by the ECL detection system (Beyotime, Shanghai, China).

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.
