Detection of Human/Mouse UCP2 by Western Blot. Western blot shows lysates of mouse brown adipose tissue. PVDF membrane was probed with 1 µg/mL Goat Anti-Human/Mouse UCP2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4739) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). For additional reference, recombinant human UCP1, UCP2, UCP3, and UCP4 (5 ng/lane) were included. A specific band for UCP2 was detected at approximately 33 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 4.
Detection of Mouse UCP2 by Simple WesternTM. Simple Western lane view shows lysates of mouse brown adipose tissue, loaded at 0.2 mg/mL. A specific band was detected for UCP2 at approximately 38 kDa (as indicated) using 10 µg/mL of Goat Anti-Human/Mouse UCP2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4739) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Mitochondrial Uncoupling Protein 2 (UCP2) is a 33 kDa member of the mitochondrial carrier protein family. UCP2 uncouples respiration from oxidative phosphorylation, principally in fat and skeletal muscle. Unlike UCP1, which generates heat in response to cold, UCP2 generates heat in response to dietary fluctuations. Human UCP2 is 309 amino acid (aa) in length. It contains six transmembrane domains (aa’s 11‑291) and is embedded in the inner mitochondrial membrane. Here, it dimerizes, forming a proton channel. There is one nucleotide binding site (aa 276‑298). Full‑length UCP2 shares 94%, 97% and 96% aa identity with porcine, canine and mouse UCP2, respectively.
