Transforming Growth Factor Beta 3 (TGF-beta 3), BioAssay(TM) ELISA Kit (Mouse)

Transforming growth factor beta 3(TGF-beta 3) is a type of protein, known as a cytokine, which is involved in cell differentiation, embryogenesis and development. It belongs to a large family of cytokines called the Transforming growth factor beta superfamily. TGF-beta 3 is believed to regulate molecules involved in cellular adhesion and extracellular matrix(ECM) formation during the process of palate development. Without TGF-beta 3, mammals develop a deformity known as acleft palate. This is caused by failure of epithelial cells in both sides of the developing palate to fuse. TGF-beta 3 also plays an essential role in controlling the development of lungs in mammals, by also regulating cell adhesion and ECM formation in this tissue, and controls wound healing by regulating the movements of epidermal and dermal cells in injured skin. TGF-beta 3 activated Lef1 in the absence of beta-catenin(CTNNB1) via nuclear phospho-Smad2 and Smad4. Sample Type: Cell culture supernates, serum, plasma (EDTA) and urine, Intended Use: For quantitative detection of activated mouse TGF-beta 3 in cell culture supernates, serum, plasma (EDTA) and urine. Sensitivity: <10pg/ml, Range: 31.2-2000pg/ml, Specificity: Natural and recombinant mouse TGF-beta 3, Test Principle: This mouse TGF-beta 3 BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for TGF-beta 3 has been precoated onto 96-well plates. Standards(sf21) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for TGF-beta 3 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse TGF-beta 3 amount of sample captured in plate.
