Purity Confirmation> 98% by SDS-PAGE & HPLC analyses
Length [aa]112
Molecular Weight25 kDa
Biological ActivityThe ED50 as determined by the cell toxicity assay using the WHO Standard 98/608 as a direct comparison is < 0.05ng/ml.
Species ReactivityHuman
Buffer% TFA
ReconstitutionCentrifuge the vial prior to opening. Reconstitute in 5-10mM Citric Acid to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
Stability and StorageThe lyophilized protein is stable at room temperature for 1 month and at 4°C for 6 months. Reconstituted working aliquots are stable for 1 week at 2°C to 8°C and for 12 months at -20°C to -80°C.
Synonyms TGFB3; ARVD; TGF-beta3
DescriptionThe three mammalian isoforms of TGF-β, TGF-β1, β2, β3, signal through the same receptor and elicit similar biological responses. They are multifunctional cytokines that regulate cell proliferation, growth, differentiation and motility as well as synthesis and deposition of the extracellular matrix. They are involved in various physiological processes including embryogenesis, tissue remodeling and wound healing. They are 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. The physiological role of TGF-β3 is still unknown but its expression pattern suggests a role in the regulation of certain development processes. Recombinant human TGF-β3 is a 25.0 kDa protein composed of two identical 112 amino acid polypeptide chains linked by a single disulfide bond.
