Used in immunological research to detect and quantify muramyl dipeptide (MDP), a component of bacterial cell walls, in biological samples. Helps study innate immune responses, particularly those involving NOD2 receptor activation. Commonly applied in investigations of inflammation, infectious diseases, and autoimmune disorders. Enables researchers to assess MDP levels in serum, tissue homogenates, and cell cultures, supporting studies on gut microbiota, sepsis, and vaccine adjuvants. Provides a reliable tool for monitoring immune activation in experimental models.
