Used in biomedical research to detect and quantify ERND (Endoribonuclease Domain) activity in human cell samples. Helps in studying RNA degradation processes and innate immune responses, particularly in relation to antiviral signaling pathways. Commonly applied in immunology and molecular biology studies to assess enzyme function in health and disease, including viral infections and autoimmune conditions. Enables high-throughput screening of potential therapeutic compounds that modulate ERND activity.
