Used to detect and quantify phosphorylated ERK (extracellular signal-regulated kinase) levels in mouse samples, this ELISA kit is essential in studying cellular signaling pathways involved in cell growth, differentiation, and apoptosis. It is widely applied in cancer research, neurobiology, and immunology to evaluate the activation status of the MAPK/ERK pathway. Researchers use it to assess the effects of drugs, growth factors, or genetic modifications on ERK signaling in mouse-derived tissues or cultured cells. The kit enables high-throughput analysis with high sensitivity and specificity, supporting both basic research and drug development.
