• 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 Insulin Like Growth Factor Binding Protein 2 (IGFBP2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Insulin Like Growth Factor Binding Protein 2 (IGFBP2). 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 Insulin Like Growth Factor Binding Protein 2 (IGFBP2), 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 Insulin Like Growth Factor Binding Protein 2 (IGFBP2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

Target Info

• Gene Symbol: IGFBP2
• Gene Full Name: insulin like growth factor binding protein 2
• Alias Symbols: IBP-2;IGF-binding protein 2;IGFBP-2;insulin-like growth factor-binding protein 2;pIGFBP-2.
• NCBI Gene Id: 397064
• Protein Name: Insulin-like growth factor-binding protein 2
• Description of Target: May have both growth-inhibiting and growth-promoting effects, depending on tissue type; increases IGF-induced DNA synthesis in the uterine epithelium. IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
