Validation Data Gallery

• 

  WB analysis using 83959-5-RR (same clone as 83959-5-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 83959-5-RR (XBP1S-specific antibody) at dilution of 1:10000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83959-5-PBS in a different storage buffer formulation.

• 

  IHC staining of mouse liver using 83959-5-RR (same clone as 83959-5-PBS)

  Immunohistochemical analysis of paraffin-embedded mouse liver tissue slide using 83959-5-RR (XBP1S-specific antibody) at dilution of 1:500 (under 40x lens). Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 83959-5-PBS in a different storage buffer formulation.

• 

  FC experiment of Ramos using 83959-5-RR (same clone as 83959-5-PBS)

  1x10^6 Ramos cells were intracellularly stained with 0.25 ug XBP1S-specific Recombinant antibody (83959-5-RR, Clone:241004B6) and APC-Conjugated AffiniPure Goat Anti-Rabbit IgG(H+L)(red), or 0.25 ug Isotype Control (blue). Cells were fixed and permeabilized with True-Nuclear Transcription Factor Buffer Set. This data was developed using the same antibody clone with 83959-5-PBS in a different storage buffer formulation.

Background Information

XBP1, also named as XBP2, belongs to the bZIP family. The X-box-binding protein-1 (XBP1) is a transcriptional regulator of the ER stress response that lies downstream of inositol-requiring enzyme 1 (IRE1α) activation (PMID: 14559994). XBP1 localizes in the nucleus. As a transcription factor, it is essential for hepatocyte growth, the differentiation of plasma cells, the immunoglobulin secretion, and the unfolded protein response. XBP1 has an association with major affective disorder. The unspliced XBP1U isoform is composed of 261 amino acid residues, and the spliced XBP1S isoform is composed of 376 amino acid residues. The calculated molecular weight of protein generated from the unspliced XBP1 isoform XBP1U mRNA is 33 kDa, and protein generated from spliced XBP1 isoform XBP1S mRNA is 54 kDa. This antibody specially recognizes the XBP1S isoform.
