Used to detect and quantify PERK (protein kinase RNA-like endoplasmic reticulum kinase) activity in mouse samples, this ELISA kit is essential in research related to endoplasmic reticulum stress and the unfolded protein response (UPR). It enables researchers to assess cellular stress pathways in diseases such as diabetes, neurodegenerative disorders, and cancer. The kit supports high-throughput analysis in preclinical studies, helping evaluate the effects of therapeutic compounds on PERK signaling. It is widely used in molecular biology and pharmacology labs to monitor pathway activation and screen potential drug candidates targeting ER stress mechanisms.
