Background	XBP-1 Antibody: X box binding protein 1 (XBP-1) is a key protein in the mammalian unfolded protein response (UPR) that protects the cell against the stress of malfolded proteins in the endoplasmic reticulum (ER). Upon sensing unfolded proteins, an ER transmembrane endonuclease and kinase termed IRE1p is activated and excises an intron from XBP-1 mRNA. The spliced XBP-1 mRNA results in a 371 amino acid protein (XBP-1s) which is then translocated to the nucleus where it binds to the regulatory elements of downstream genes. Together with other UPR transcription factors such as ATF6, XBP-1 stimulates the production of ER stress proteins including the ER resident protein chaperones glucose regulated protein (GRP) 78 and GRP94.

Purification	XBP-1 Antibody is affinity chromatography purified via peptide column.
Isoforms	Human XBP-1 has two isoforms, including isoform 1 (261aa, 29kD) and isoform 2 (376aa, 40kD). Mouse XBP-1 also has two isoforms, including isoform 1 (267aa, 29.6kD) and isoform 2 (371aa, 40kD). And Rat XBP-1 has two isoforms as well, including isoform 1 (267aa, 30kD) and isoform 2 (371aa, 40kD). 3687 can detect human, mouse and rat.

Disclaimer	Optimal dilutions/concentrations should be determined by the end user. The information provided is a guideline for product use. This product is for research use only.
Validation	KO Validation (Figure 2): XBP-1 expression detected by anti-XBP-1 antibodies was observed in wild type HeLa cells, but not in the XBP-1 knockout HeLa cells. Recombinant Protein Test (Figure 3): Anti-XBP-1 antibodies (3687) detected human XBP-1 recombinant protein at different concentrations.
