Transforming Growth Factor beta 2 (TGFb2, TGFB2, BSC-1 cell growth inhibitor, Cetermin, Glioblastoma

Human Transforming Growth Factor beta2 (TGF- beta2) is stimulatory for cells of mesenchymal origin and inhibitory for cells of epithelial or neuroectodermal origin. Mature TGF- beta2 is a disulfide-linked homodimer of two chains composed of 112 aa residues each. There is a 70% homology between human TGF- beta2 and human TGF- beta1. Source: bacteria, Biological Activity: The biological activity of human TGF-&# beta2 is determined by measuring the acidification of the culture medium (Rat-1 cells) exposed to the growth factor. Storage and Stability: Lyophilized powder may be stored at -20°C. Reconstitute to with sterile dH2O or buffer, aliquot and store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
