Used in biomedical research to detect and quantify the activation levels of mitogen-activated protein kinases (MAPK) in human cell or tissue samples. This ELISA kit enables researchers to study intracellular signaling pathways involved in cell proliferation, differentiation, stress response, and apoptosis. Commonly applied in studies related to cancer, inflammation, and neurodegenerative diseases to assess phosphorylation states of MAPK proteins. Provides a high-throughput, sensitive, and specific method for monitoring kinase activity in response to drugs, growth factors, or environmental stimuli. Widely used in pharmaceutical development and molecular biology labs for signal transduction analysis.
