Used to measure phosphorylated ERK (pERK) levels in rat samples, this ELISA kit is essential for studying cellular signaling pathways, particularly the MAPK/ERK pathway involved in cell proliferation, differentiation, and apoptosis. It is widely applied in neuroscience research to assess neuronal activation and in pharmacology to evaluate drug effects on intracellular signaling. The kit enables high-throughput, quantitative analysis of pERK in tissue lysates or cell extracts, supporting research in neurodegenerative diseases, cancer, and inflammation. Its specificity allows accurate detection of activated ERK, making it a valuable tool in preclinical studies and biomarker development.
