Used in immunological research to quantify MICB protein levels in human biological samples such as serum, plasma, and cell culture supernatants. Helps in studying immune responses, particularly in conditions involving NK cell and T cell activation, as MICB is a stress-induced ligand for the NKG2D receptor. Widely applied in cancer research, autoimmune diseases, and transplant immunology to assess cellular stress and immune surveillance. The kit enables high-throughput, accurate measurement of soluble MICB, supporting biomarker discovery and monitoring disease progression or therapeutic response.
