Used in biomedical research to quantify levels of PERK protein in mouse samples, particularly in studies related to endoplasmic reticulum (ER) stress and the unfolded protein response (UPR). Helps researchers investigate cellular stress pathways in diseases such as diabetes, neurodegenerative disorders (e.g., Alzheimer's and Parkinson's), and cancer. Enables assessment of PERK activation in response to experimental treatments, making it valuable in drug development and mechanistic studies involving signaling pathways. Widely applied in immunology, molecular biology, and pharmacology research settings.
