Used to measure mitogen-activated protein kinase (MAPK) activity in rat samples, this ELISA kit is widely applied in biomedical research to study cellular responses such as proliferation, differentiation, and apoptosis. It is commonly used in pharmacology and toxicology studies to evaluate drug effects on signaling pathways. Researchers also use it in inflammation and cancer studies to understand molecular mechanisms in rat models. The kit enables high-throughput analysis, making it suitable for screening compounds that modulate MAPK signaling.
