Used in biomedical research to quantify levels of human alpha-2-macroglobulin (α2-MG) in biological samples such as plasma, serum, and cell culture supernatants. This ELISA kit enables researchers to study α2-MG's role in protease inhibition, inflammation, and immune response modulation. It is particularly useful in clinical studies investigating conditions like liver disease, kidney disorders, cancer, and neurodegenerative diseases where α2-MG levels may be altered. The assay provides a sensitive and specific means to monitor changes in α2-MG concentration, supporting both diagnostic research and therapeutic development.
