Transcription factor essential for hepatocyte growth, the differentiation of plasma cells, the immunoglobulin secretion, and the unfolded protein response (UPR). Acts during endoplasmic reticulum stress (ER) by activating unfolded protein response (UPR) target genes via direct binding to the UPR element (UPRE). Binds DNA preferably to the CRE-like element 5'-GATGACGTG[TG]N3[AT]T-3', and also to some TPA response elements (TRE). Binds to the HLA DR-alpha promoter. Binds to the Tax-responsive element (TRE) of HTLV-I.

Applications
Suitable for use in ELISA and Western Blot. Other applications not tested.
Recommended Dilution
ELISA: 1:4000 Western Blot: 1-3ug/ml, observed in nuclear lysates of cell line HeLa on ~38kD bands Optimal dilutions to be determined by the researcher.
Storage and Stability
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Immunogen
Synthetic peptide corresponding to C-NHSWEDTFANELFPQ, from human XBP1, at the internal region of the protein (NP_001073007.1).
Form
Supplied as a liquid in Tris saline, 0.02% sodium azide, pH 7.3, 0.5% BSA.
Purity
Purified by immunoaffinity chromatography.
Specificity
Recognizes human XBP1. Species sequence homology: Canine.
