Used in molecular biology and biomedical research to quantify the phosphorylation levels of eIF2α in mouse cell or tissue samples. This kit enables researchers to study cellular stress responses, as phosphorylated eIF2α plays a key role in the integrated stress response pathway. It is commonly applied in neuroscience, cancer research, and metabolic disease studies to understand how stress signaling affects cell function and survival. The assay provides a reliable and sensitive method for measuring eIF2α activation in experimental models, supporting investigations into drug effects, neurodegenerative diseases, and viral infection mechanisms.
