Used for quantifying manganese superoxide dismutase (Mn-SOD) enzyme activity in human biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to assess antioxidant capacity and oxidative stress levels in clinical and research settings. It is commonly applied in studies related to aging, neurodegenerative diseases, cardiovascular disorders, and inflammatory conditions where oxidative damage plays a key role. The assay provides a sensitive and specific measurement of Mn-SOD function, supporting biomarker development and evaluation of therapeutic interventions targeting redox balance.
