Glutathione Peroxidase 2 (GPX2), also known as Gastrointestinal Glutathione Peroxidase, is a member of the glutathione peroxidase antioxidant enzyme family. These proteins protect cell surfaces, extracellular fluid components, and enzymes from oxidative stress by reducing hydrogen peroxide, lipid peroxides, and organic hydroperoxide using reduced glutathione. GPX2 is a cytoplasmic homotetramer of 22 kDa subunits, each containing a selenocysteine residue at the active site. GPX2 is primarily expressed in the liver and intestinal epithelial cells where it participates in the detoxification of dietary organic hydroperoxides. It is upregulated in a variety of carcinomas and functions as an anti-inflammatory and anti-apoptotic molecule. Over amino acids 41‑190, human GPX2 shares 94% aa sequence identity with mouse and rat GPX2.

Detection of Human/Mouse/Rat Glutathione Peroxidase 2 by Western Blot.
Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, human liver tissue, Hepa 1-6 mouse hepatoma cell line, and rat liver tissue. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat Glutathione Peroxidase 2 Monoclonal Antibody (Catalog # MAB5470) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Glutathione Peroxidase 2 at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.Detection of Rat Glutathione Peroxidase 2/GPX2 by Western Blot
Expression of various ROS-related proteins, pro-inflammatory factors, and an osteoclast differentiation factor RANKL in tissue samples of all treated groups at 24 weeks after surgery.(A) Representative Western blot analysis of transferrin, catalase, SOD1, SOD2, SOD3, GPx1, GPx2, TTR, NF-kappa B, IL-1 beta and RANKL in different groups. GAPDH was used as internal control. (B) Densitometric quantification of Western blot analysis for all tested proteins normalized to GAPDH (n = 3 for each group). *, P < 0.05, for results compared to those of the sham group; #, P < 0.05, for results compared to those of the group receiving an artificial knee joint only.
