Used in biomedical research to detect and quantify phosphorylated extracellular signal-regulated kinase (p-ERK) in rabbit tissue or cell lysates. This kit is essential for studying cellular signaling pathways involved in cell growth, differentiation, and apoptosis. Commonly applied in neuroscience, cancer research, and pharmacology to evaluate the activation status of the MAPK/ERK pathway in response to stimuli such as growth factors, stress, or drug treatments. Enables high-throughput analysis in microplate format, providing a sensitive and specific measurement of p-ERK levels without the need for radioactivity or Western blotting.
