Our Abpromise guarantee covers the use of ab10518 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: For immunoblotting, a working concentration of 0.1 to 0.2 µg/ml antibody is recommended. The detection limit for recombinant human TGF beta 1 is approximately 1 ng/lane and 5 ng/lane under non-reducing and reducing conditions, respectively. Predicted molecular weight: 47 kDa for the unprocessed precursor; 25 kDa for the mature protein.
Inhib: Anti-Human TGF beta 1 neutralises the bioactivity of recombinant human TGF beta 1 by inhibiting cell proliferation using the IL4 dependent murine HT-2 cell line.
In this bioassay, recombinant human TGF beta 1 (0.25 ng/ml) is preincubated with various cencentrations of the antibody (0.1 to 1000 ng/ml) for 1 hour at room temperature in a 96-well microtiter plate. Following this pre-incubation, HT-2 cells are added to each well. The total volume of 100 µl, containing antibody at various concentrations, recombinant mouse IL-4 at 7.5 ng/ml, recombinant human TGF-Beta-1 at 0.25 ng/ml, and HT-2 cells at 1 x 105 cells/ml, is incubated for 48 hours at 37 °C in a 5 % CO2 humidified incubator. 3H-thymidine is added during the final four hours. Cells are harvested onto glass filters and the 3H-thymidine incorporated into DNA is measured.
The Neutralization Dose50 (ND50) for anti-human TGF beta 1 is approximately 5 to 10 ng/ml in the presence of 0.25 ng/ml of recombinant human TGF beta 1, using the murine HT-2 cell line. The ND50 of this antibody is defined as the concentration of antibody resulting in a one-half maximal inhibition of bioactivity of recombinant human TGF beta 1 that is present at a concentration just high enough to elicit a maximum response. The exact concentration of antibody required to neutralize recombinant human TGF beta 1 activity is dependent on the cytokine concentration, cell type, growth conditions, and the type of activity studied.

- FunctionMultifunctional protein that controls proliferation, differentiation and other functions in many cell types. Many cells synthesize TGFB1 and have specific receptors for it. It positively and negatively regulates many other growth factors. It plays an important role in bone remodeling as it is a potent stimulator of osteoblastic bone formation, causing chemotaxis, proliferation and differentiation in committed osteoblasts.
- Tissue specificityHighly expressed in bone. Abundantly expressed in articular cartilage and chondrocytes and is increased in osteoarthritis (OA). Co-localizes with ASPN in chondrocytes within OA lesions of articular cartilage.
- Involvement in diseaseDefects in TGFB1 are the cause of Camurati-Engelmann disease (CE) [MIM:131300]; also known as progressive diaphyseal dysplasia 1 (DPD1). CE is an autosomal dominant disorder characterized by hyperostosis and sclerosis of the diaphyses of long bones. The disease typically presents in early childhood with pain, muscular weakness and waddling gait, and in some cases other features such as exophthalmos, facial paralysis, hearing difficulties and loss of vision.
- Sequence similaritiesBelongs to the TGF-beta family.
The precursor is cleaved into mature TGF-beta-1 and LAP, which remains non-covalently linked to mature TGF-beta-1 rendering it inactive.
