Used in research settings to quantitatively measure β2-microglobulin levels in biological samples such as serum, plasma, urine, and cell culture supernatants. The kit enables assessment of immune system activity and kidney function, as elevated β2-microglobulin is associated with conditions like chronic inflammation, autoimmune diseases, and renal impairment. It is also employed in oncology research, particularly in monitoring multiple myeloma and other hematologic malignancies. The ELISA format allows for high sensitivity and specificity, making it suitable for detecting low concentrations of β2-microglobulin in small sample volumes. Widely used in clinical laboratories and biomedical research for diagnostic development and disease progression studies.
