Synonyms
Transforming growth factor beta-1, TGF-beta-1, CED, DPD1, TGFB, TGF-b 1, LAP, TGFB1.
Description
TGFB1 Human Recombinant produced in 293 cells is a glycosylated homodimer polypeptide chain containing 2 x 112 amino acids and having a total molecular mass of 25.0kDa. The TGFB1 is purified by proprietary chromatographic techniques.
Source
HEK 293 cells.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a sterile filtered solution containing TFA (0.1%).
Solubility
It is recommended to reconstitute the lyophilized TGFB1 in sterile in 18MΩ-cm H2O at a concentration of 0.1 mg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized TGFB1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TGFB1 Human should be stored at 4°C between 2-7 days and for future use below -18°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Purity
Greater than 98.0% as determined by: (a) Analysis by HPLC. (b) Analysis by SDS-PAGE.

Background
Transforming growth factor betas (TGF Betas) mediate many cell-cell interactions that occur during embryonic development. 3 TGF Betas have been identified in mammals: TGF Beta 1, TGF Beta 2 and TGF Beta 3. each are synthesized as precursor proteins that are very similar in that each is cleaved to yield a 112 amino acid polypeptide that remains associated with the latent portion of the molecule.
