Used in biomedical research to detect and quantify phosphorylated PERK protein levels in mouse cell or tissue samples. This kit is essential for studying endoplasmic reticulum (ER) stress and the unfolded protein response (UPR), which are involved in various cellular processes including apoptosis, inflammation, and metabolic regulation. Researchers use it in neuroscience, cancer, diabetes, and neurodegenerative disease studies to understand how ER stress contributes to disease development and progression. The assay provides a reliable and sensitive method for monitoring PERK activation, enabling evaluation of potential therapeutic agents targeting ER stress pathways.
