Detection of Human/Mouse/Rat SOD2/Mn-SOD by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, and L6 rat myoblast cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse/Rat SOD2/Mn-SOD Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3419) followed by HRP‑conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for SOD2/Mn-SOD at approximately 23 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 2.
Detection of Human and Mouse SOD2/Mn‑SOD by Simple WesternTM. Simple Western lane view shows lysates of HepG2 human hepatocellular carcinoma cell line and NIH‑3T3 mouse embryonic fibroblast cell line, loaded at 0.2 mg/mL. A specific band was detected for SOD2/Mn‑SOD at approximately 28 kDa (as indicated) using 10 µg/mL of Goat Anti-Human/Mouse/Rat SOD2/Mn‑SOD Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3419) 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.

Superoxide Dismutases (SODs), originally identified as Indophenoloxidases (IPOs), are enzymes that catalyze the conversion of naturally occurring but harmful superoxide radicals into molecular oxygen and hydrogen peroxide. Superoxide Dismutases 2 (SOD2, also known as Manganese (Mn) SOD, mitochondrial SOD and IPO-B) is an intramitochondrial 23 kDa protein that associates as a homotetramer. Each SOD2 monomer binds one Mn2+ ion. Oxidative stress has been implicated in many diseases and the chief source of reactive oxygen species within the cell is the mitochondrion. SOD2 is a free radical scavenging enzyme that protects against damage from superoxide produced as a byproduct of oxidative phosphorylation and protects the integrity of mitochondrial enzymes susceptible to inactivation by superoxide. Over aa 25‑222, human SOD2 shows 94% and 93% identity to mouse and rat SOD2.
