Used in biomedical research to quantify levels of 20S proteasome in rat samples, this ELISA kit enables detection of proteasome activity associated with protein degradation pathways. It is applied in studies of oxidative stress, muscle wasting, neurodegenerative diseases, and aging, where abnormal protein turnover occurs. Researchers use it to assess cellular damage and evaluate efficacy of therapeutic compounds targeting proteolytic systems. The assay provides a sensitive and specific measurement in tissue homogenates, blood, or cell lysates, supporting investigation into disease mechanisms and drug development.
