配列の追加情報TGF-beta1 is a 25.0 kDa protein with each subunit containing 112 aa, linked by a single disulfide bond. It is the mature protein after cleavage of the signal peptide and latency-associated peptide.
Our Abpromise guarantee covers the use of ab50036 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
TGF-beta is secreted predominantly as latent complexes which are stored at the cell surface and in the extracellular matrix.
The release of biologically active TGF-β isoform from a latent complex involves proteolytic processing of the complex and /or induction of conformational changes by proteins such as thrombospondin-1.
TGF-β1 is the most abundant isoform secreted by almost every cell type.
Concentration information loading...
Shipped at 4°C. Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.
Endotoxin level is less than 0.1 ng per µg (1EU/µg).
This product is an active protein and may elicit a biological response in vivo, handle with caution.
再構成Centrifuge the vial prior to opening. Reconstitute in 10mM Citric Acid, pH3.0 to a concentration of 50 µg/ml (e.g. 5 µg/100µl). This solution can then be stored at room temperature or at 4oC for 1 month. It is recommended that further dilutions be made in PBS containing 2 mg/ml albumin and stored at -20oC for future use.
- Cartilage-inducing factor
- Differentiation inhibiting factor
機能Multifunctional 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.
組織特異性Highly 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.
関連疾患Defects 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.
配列類似性Belongs 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.
