Used to detect and quantify ERK (extracellular signal-regulated kinase) activity in mouse cell or tissue samples. This ELISA kit enables researchers to measure phosphorylation levels of ERK proteins, which are key indicators of activation in signaling pathways involved in cell growth, differentiation, and apoptosis. Commonly applied in studies of cancer, neurodegenerative diseases, and inflammatory conditions to assess pathway modulation in response to drugs or genetic changes. Suitable for high-throughput screening and provides a reliable, sensitive method for monitoring intracellular signaling events in preclinical research.
