Name: Human transforming growth factor beta-1 (TGF beta-1) recombinant
Price: 560.00 USD

- Overview
  - 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 112 amino acid residues each. There is a 70% homology between human TGF- beta1 and human TGF- beta2. Human TGF- beta1 is produced in genetically engineered bacteria, and purified by sequential chromatography.

- Properties
  - Type
    
    Recombinant Proteins
    
    Purification
    
    Over 98% pure by non-reduced SDS gel electrophoresis.
    
    Formulation
    
    25 µl (0.20 mg/ml) in 5 mM HCl (pH 2.5). Some of the liquid in the vial could have been evaporated with changes in the final volume. However, the 5µg of the protein are still inside the vial. We recommend, in order to control the proper concentration, to dilute the entire content to a known volume with 5mM HCl. Do not freeze this material.
    
    Storage
    
    Store at +4°C.
    
    Molecular Weight
    
    25 KDa (dimeric protein)
    
    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.
    
    * For research use ONLY in laboratory animals and in vitro testing. NOT for diagnostic or human use.
