Transforming Growth Factor beta 1 (TGFb2,TGFB1, CED, DPD1, TGFB, TGF-beta-1, Transforming Growth Fac

Human Transforming Growth Factor beta1 (TGF-beta1) is stimulatory for cells of mesenchymal origin and inhibitory for cells of epithelial or neuroectodermal origin. Mature TGF-beta1 is a disulfide-linked homodimer of two chains composed of 112aa residues each. There is a 70% homology between human TGF-beta1 and human TGF-beta2. Biological Activity: The biological activity of human TGF-beta1 is determined by measuring the acidification of the culture medium (Rat-1 cells) exposed to the growth factor. Storage and Stability: May be stored at 4°C. For long-term storage, aliquot and store at 4°C. Do not freeze. Aliquots are stable for at least 6 months. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
