Description: Recombinant human TGF-beta 3 is a 27.2 kDa protein composed of two identical 118 amino acid peptide chains linked by a single disulfide bond. Transforming growth factor-beta is a family of five related cytokines that have been shown on a wide variety of normal and neoplastic cells, indicating the importance of these homo-dimmer proteins as multi-functional regulators of cellular activity. The three mammalian isoforms of TGF-beta (TGF-beta 1, TGF-beta 2 and TGF-beta 3) signal through the same receptor and elicit similar biological responses. They are involved in physiological processes as embryogenesis, tissue remodelling and wound healing. Source: It is produced by transient expression of TGF-beta 3 in non-transgenic plants. Recombinant human TGF-beta 3 contains a 6-His-tag at the N-terminal end and is purified by sequential chromatography (FPLC). This product contains no animal derived components or impurities.
