Product Information

Product Description

This Cell Signaling Technology antibody is conjugated to Alexa Fluor^® 488 fluorescent dye and tested in-house for direct flow cytometric analysis in mouse cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated XBP-1s (E9V3E) Rabbit mAb # 40435.

Product Usage Information

Application	Dilution
Flow Cytometry (Fixed/Permeabilized)	1:50

Storage

Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

Protocol

Specificity / Sensitivity

XBP-1s (E9V3E) Rabbit mAb (Alexa Fluor^® 488 Conjugate) recognizes endogenous levels of total XBP-1s protein. In western blot analysis, the antibody detects a 78 kDa protein and a 99 kDa protein of unknown identities.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala361 of mouse XBP-1s protein.

Background

Following protein synthesis, secretory, intra-organellar, and transmembrane proteins translocate into the endoplasmic reticulum (ER) where they are post-translationally modified and properly folded. The accumulation of unfolded proteins within the ER triggers an adaptive mechanism known as the unfolded protein response (UPR) that counteracts compromised protein folding (1). The transmembrane serine/threonine kinase IRE1, originally identified in Saccharomyces cerevisiae, is a proximal sensor for the UPR that transmits the unfolded protein signal across the ER membrane (2-4). The human homolog IRE1α was later identified and is ubiquitously expressed in human tissues (5). Upon activation of the unfolded protein response, IRE1α splices X-box binding protein 1 (XBP-1) mRNA through an unconventional mechanism using its endoribonuclease activity (6). This reaction converts XBP-1 from an unspliced XBP-1u isoform to the spliced XBP-1s isoform, which is a potent transcriptional activator that induces expression of many UPR responsive genes (6).
