Detection of XBP1S in RPMI 8226 Human Cell Line by Flow Cytometry. RPMI 8226 human multiple myeloma cell line was stained with Mouse Anti-Human XBP1S Monoclonal Antibody (Catalog # MAB4257, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG F(ab')2 Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

X-box binding protein 1 (XBP1; also tax-responsive element-binding protein 5 (TREB5) is a ubiquitously expressed member of the bZIP family of proteins. The spliced form of XBP1 (XBP1S) is a 376 amino acid (aa), 55 kDa transcription factor essential for the unfolded protein response. XBP1S is formed during endoplasmic reticulum stress by IRE-1-mediated splicing that creates a 210 aa substitution for XBP1 aa 161-261. XBP1S contains a basic DNA binding motif (aa 72-94) and a leucine-zipper domain (aa 98-126). Within the region used as an immunogen, human XBP1S shares 96% aa sequence identity with mouse XBP1S.
