Used to measure extracellular signal-regulated kinase (ERK) activity in rat samples, this ELISA kit is essential in research settings focused on cell signaling pathways. It enables scientists to quantify phosphorylated ERK levels, providing insight into the activation status of the MAPK pathway. Commonly applied in studies of inflammation, cancer, neurodegenerative diseases, and drug development, the kit supports high-throughput analysis with high sensitivity and specificity. It is widely used in pharmaceutical research and academic laboratories to evaluate cellular responses to stimuli such as growth factors, cytokines, and therapeutic agents.
