Used in biomedical research to detect and quantify MEK protein levels in rat samples, this ELISA kit enables study of the MAPK signaling pathway, which plays a key role in cell proliferation, differentiation, and apoptosis. It is widely applied in neuroscience, cancer research, and drug development to assess MEK activation states and evaluate the effects of therapeutic compounds on kinase activity in rat models. The assay provides a sensitive and specific method for measuring MEK in tissue lysates, cell cultures, or biological fluids, supporting high-throughput screening and mechanistic studies in experimental biology.
