Used in biomedical research to detect and quantify X-box binding protein levels in mouse samples, this ELISA kit enables scientists to study cellular stress responses, particularly the unfolded protein response (UPR) in immune cells and secretory tissues. It is widely applied in investigations of inflammation, metabolic diseases, cancer, and autoimmune disorders. Researchers use it to assess activation of the IRE1α-XBP1 signaling pathway, helping to understand disease mechanisms and evaluate potential therapeutic interventions in preclinical models. The kit provides a reliable and sensitive method for measuring both unspliced and spliced forms of XBP1, allowing differentiation between inactive and active states of the protein.
