Transforming growth factor beta-1 (TGF beta 1) is a homodimeric protein that regulates the proliferation and differentiation of normal and transformed cells. TGF beta 1 is the most abundant isoform which is secreted by most cell types.

Target Species
Product Form
Purified recombinant protein - lyophilized
Reconstitute with 100ul distilled water. Further dilutions should be made in buffer containing a carrier protein such as 0.1% BSA.
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution. DO NOT VORTEX.
Recombinant protein prepared from CHO cells.
CHO cells
Preservative Stabilisers
None present
Carrier Free
The ED50, determined by the ability of TGF beta 1 to inhibit the mouse IL-4-dependent proliferation of mouse HT-2 cells is ≤0.05 ng/ml, corresponding to a specific activity of ≥2 x 107 units/mg
>98% by SDS PAGE and HPLC analysis
Approx. Protein Concentrations
0.1 mg/ml after reconstitution
Protein Molecular Weight
25.0 kDa (2x identical 112 amino acid polypeptide chains)
Endotoxin Level
< 0.1 ng/ug
For research purposes only
Guaranteed for 3 months from the date of reconstitution or until the date of expiry, whichever comes first. Please see label for expiry date.

Prior to reconstitution store at -20oC. Following reconstitution store at -20oC.

This product should be stored undiluted.

Storage in frost-free freezers is not recommended. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.
