Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-XBP1 antibody (AB37152)
ab37152 staining XBP1 in human liver tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with formaldehyde and a heat mediated antigen retrieval step was performed using Citrate-EDTA antigen retrieval buffer and microwave. Heating was performed in the microwave 3 minutes on high until boiling, 6 minutes on 20% power. Samples were then blocked for 15 minutes at 27°C followed by incubation with the primary antibody at a 1/100 dilution for 12 hours at 4°C. An undiluted HRP-conjugated rat polyclonal was used as the secondary antibody.

Biological function summary
The action of XBP1 participates in processes critical for cell survival under stress conditions particularly in the UPR. It activates genes involved in protein folding secretion and degradation to alleviate stress within the endoplasmic reticulum. XBP1 acts as part of the larger mechanism that ensures cellular homeostasis by maintaining protein quality control. It forms a complex network with other transcription factors ensuring an integrated response to stress stimuli in various tissues including pancreatic beta cells and immune cells.
Pathways
XBP1 functions intricately within the UPR and is linked to the insulin signaling pathway. It works alongside proteins such as ATF6 and PERK to coordinate the cellular response to endoplasmic reticulum stress and sustain essential cellular processes. The IRE1-XBP1 pathway represents one arm of the UPR and shows interaction with C/EBP homologous protein (CHOP) as part of the stress signaling pathways modulating apoptosis if adaptation fails. XBP1 also influences lipid metabolism and cellular differentiation through its pathway connections impacting wide-ranging physiological processes.
