The spliced form of X-box binding protein 1 (XBP1s) is an active transcription factor that plays a vital role in the unfolded protein response (UPR). In response to endoplasmic reticulum stress and UPR, BiP relaxes its inhibitory binding to trigger IRE1. After dimerizing and auto-phosphorylating, the IRE1 receptor initiates its mRNase activity. In order to facilitate XBP-1u mRNA's translation and subsequent translocation to the nucleus, IRE1 splices it into XBP1s. Afterward, XBP-1 functions as a transcription factor. XBP1s is an important therapeutic target in studying various diseases, including cancer, diabetes, and autoimmune and inflammatory diseases.
The AlphaLISA SureFire Ultra Human Total XBP1s Detection Kit is a sandwich immunoassay for the quantitative detection of total XBP1s in cellular lysates, using Alpha Technology.

The Total-AlphaLISA SureFire Ultra assay measures the expression level of a protein target in a cell lysate.
The Total-AlphaLISA SureFire Ultra assay uses two antibodies which recognize two different distal epitopes on the targeted protein. AlphaLISA assays require two bead types: Acceptor and Donor beads. Acceptor beads are coated with a proprietary CaptSure™ agent to specifically immobilize the assay specific antibody, labeled with a CaptSure tag. Donor beads are coated with streptavidin to capture one of the detection antibodies, which is biotinylated. In the presence of targeted protein, the two antibodies bring the Donor and Acceptor beads in close proximity whereby the singlet oxygen transfers energy to excite the Acceptor bead, allowing the generation of a luminescent Alpha signal. The amount of light emission is directly proportional to the quantity of protein present in the sample.
The two-plate protocol involves culturing and treating the cells in a 96-well plate before lysis, then transferring lysates into a 384-well OptiPlate™ plate before the addition of Total-AlphaLISA SureFire Ultra detection reagents. This protocol permits the cells viability and confluence to be monitored. In addition, lysates from a single well can be used to measure multiple targets.
Detection of Total target protein with AlphaLISA SureFire Ultra reagents can be performed in a single plate used for culturing, treatment, and lysis. No washing steps are required. This HTS designed protocol allows for miniaturization while maintaining AlphaLISA SureFire Ultra quality.
