Used in biomedical research to detect and quantify extracellular signal-regulating kinase (ERK) protein activity in cell lysates or tissue samples. This kit enables researchers to study ERK signaling pathways involved in cell proliferation, differentiation, and apoptosis. Commonly applied in cancer research, neurobiology, and drug development to assess the impact of treatments or genetic modifications on ERK activation. Provides a reliable, sensitive, and high-throughput method for measuring phosphorylated and total ERK levels, supporting mechanistic studies in cellular signaling.
