Immunogen:Synthetic Peptide within Human Extracellular superoxide dismutase [Cu-Zn] aa 1-50. The exact immunogen used to generate this antibody is proprietary information.P08294,
Specificity:Specific to human extracellular SOD (SOD3). Under reducing conditions the SOD3 antibody shows a major band at approximately 30kDa which is the approximate molecular weight of the SOD3 monomer and two faint minor bands at approximately 50 and 70 kDa. The SOD3 molecule is a homotetramer (4 monomers) with a combined molecular weight of around a 130 Kda. The two faint bands are probably dimers and triplicates of the monomer. This pattern is common with many tetramers (such as cellular glutathione peroxidase) as there is incomplete reduction with DTT.

Superoxide Dismutase 3 also known as EC-SOD is an antioxidant enzyme with a molecular weight of approximately 135 kDa. It's an extracellular enzyme that catalyzes the dismutation of superoxide radicals into hydrogen peroxide and molecular oxygen. EC-SOD is found mostly in the extracellular matrix tissues such as lungs blood vessels and heart. Its activity depends on the presence of metal ions copper and zinc leading its classification as a Cu/Zn SOD enzyme. Scientists often study EC-SOD using ELISA assays because of its importance in neutralizing reactive oxygen species.
Biological function summary
The enzyme acts as an important regulator of oxidative stress by reducing levels of superoxide radicals. EC-SOD forms a complex with heparan sulfate proteoglycans in the extracellular matrix which influences its stability and distribution. This enzyme plays a role in maintaining the redox balance influencing cell signaling inflammation and tissue damage which makes it important in managing oxidative stress in different tissues including the cardiovascular and respiratory systems.
Pathways
Superoxide dismutase 3 participates in antioxidant pathways important for cellular defense against oxidative stress. It is particularly important in the oxidative stress response pathway. By reducing superoxide radicals EC-SOD influences pathways involving other antioxidant proteins like catalase and glutathione peroxidase. These interactions help prevent the accumulation of harmful oxidants and maintain cellular homeostasis. EC-SOD's action connects closely with other superoxide dismutases such as Cu/Zn SOD and MnSOD within these protective pathways.
Enhanced or impaired EC-SOD function associates with various health issues such as cardiovascular diseases and chronic obstructive pulmonary disease (COPD). EC-SOD has been shown to protect vascular health by reducing oxidative stress related damages which can mitigate the risk of atherosclerosis. In the context of respiratory conditions like COPD alterations in EC-SOD expression can disrupt lung tissue function and inflammatory responses. Its interactions with proteins like catalase further contribute to its protective role against cell and tissue damage during disease progression.
