Used to measure phosphorylated extracellular signal-regulated kinase (pERK) levels in cell lysates and tissue extracts. This kit is widely applied in signal transduction research, particularly in studies involving the MAPK pathway. It supports investigation of cellular responses to growth factors, hormones, and stress stimuli. Commonly used in cancer research to evaluate activation status of ERK in tumor cells, aiding in the development and monitoring of targeted therapies such as kinase inhibitors. Also utilized in pharmacology and toxicology to assess drug effects on intracellular signaling pathways. Suitable for high-throughput screening and quantitative analysis in preclinical studies.
