Used in biomedical research to detect and quantify mitogen-activated protein kinase (MAPK) activity in rat samples. This ELISA kit enables researchers to study signaling pathways involved in cellular responses such as proliferation, differentiation, and apoptosis. Commonly applied in studies of inflammation, stress responses, and cancer development. Suitable for analyzing tissue extracts, cell lysates, and biological fluids. Provides a reliable and sensitive method for monitoring MAPK activation states in experimental models, supporting drug development and mechanistic studies in pharmacology and molecular biology.
