Mice were sacrificed at 16 weeks, following the start of DIO. Mouse EWAT, liver, and pancreas were fixed in 4% paraformaldehyde, embedded in paraffin, sectioned, and stained with hematoxylin and eosin (H&E) (Sigma Aldrich, St. Louis, MO) for routine histological analysis. For immunohistochemistry (IHC), 5 μm sections of paraffin-embedded EWAT were treated with Proteinase K for 30 min, and blocked with 5% BSA and 0.5% Tween 20 for another 30 min at room temperature. To examine the degree of macrophage infiltration, EWAT, liver, and pancreas sections were incubated with macrophage marker antibody (RM0029-11H3; Santa Cruz Biotechnology, CA) at room temperature for 1 h. Isotype control antibodies (Sigma Aldrich, St. Louis, MO) were used as a negative control. Each slide was washed three times in phosphate buffered saline with Tween 20 (PBST). After the final wash step, the staining was visualized using the EnVision TM Detection System (Dako, Glostrup, Denmark) in a humid chamber for 30 min. Positive cells were detected using 3,3'diaminobenzidine tetrahydrochloride (DAB; Vector Laboratories, San Francisco, CA).

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.
