• ELISA Kit Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to X-Box Binding Protein 1 (XBP1). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to X-Box Binding Protein 1 (XBP1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain X-Box Binding Protein 1 (XBP1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of X-Box Binding Protein 1 (XBP1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Target Info

• Gene Symbol: Xbp1
• Gene Full Name: X-box binding protein 1
• Alias Symbols: hepatocarcinogenesis-related transcription factor;HTF;X-box-binding protein 1.
• NCBI Gene Id: 289754
• Protein Name: X-box-binding protein 1
• Description of Target: Functions as a transcription factor during endoplasmic reticulum (ER) stress by regulating the unfolded protein response (UPR). Required for cardiac myogenesis and hepatogenesis during embryonic development, and the development of secretory tissues such as exocrine pancreas and salivary gland. Involved in terminal differentiation of B lymphocytes to plasma cells and production of immunoglobulins. Modulates the cellular response to ER stress in a PIK3R-dependent manner. Binds to the cis-acting X box present in the promoter regions of major histocompatibility complex class II genes. Involved in VEGF-induced endothelial cell (EC) proliferation and retinal blood vessel formation during embryonic development but also for angiogenesis in adult tissues under ischemic conditions. Functions also as a major regulator of the UPR in obesity-induced insulin resistance and type 2 diabetes for the management of obesity and diabetes prevention.
