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.
