Used in biomedical research to quantify levels of the 26S proteasome in human cell lysates, tissues, or biological fluids. This kit enables researchers to assess proteasome activity and expression in studies related to protein degradation, cellular regulation, and disease mechanisms such as cancer, neurodegenerative disorders, and autoimmune diseases. It supports high-throughput screening and therapeutic development by providing a reliable method to monitor changes in proteasome levels during drug treatment or disease progression.
