Specifications

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.
Catalog #T8250-13G
Biological ActivityThe biological activity of human TGF-beta1 is determined by measuring the acidification of the culture medium (Rat-1 cells) exposed to the growth factor.
