Used in immunology and biomedical research to quantitatively measure mouse β2-microglobulin levels in biological samples such as serum, plasma, urine, and cell culture supernatants. The kit is particularly valuable in studies related to immune system activation, as β2-microglobulin is a component of major histocompatibility complex (MHC) class I molecules. It is commonly used in research involving autoimmune diseases, viral infections, cancer, and transplant rejection in mouse models. The ELISA format allows for high sensitivity and specificity, enabling researchers to monitor disease progression or evaluate therapeutic interventions in preclinical studies.
