Transforming growth factor betas (TGF-betas) mediate many cell-cell interactions that occur during embryonic development. Three TGF-betas have been identified in mammals. TGF-beta 1, TGF-beta 2 and TGF-beta 3 are each 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. Human recombinant TGF-beta 1 produced in E. coli is a single, non-glycosylated polypeptide chain of 113 amino acids (279-390 a.a.), having a total molecular mass of 12.9 kDa.

CAT# CSC-CTK0324-10 (10 μg); CAT# CSC-CTK0324-50 (50 μg)
Greater than 95% as determined by SDS-PAGE analysis.
Sterile-filtered, colorless solution (0.5 mg/ml) in 10 mM sodium citrate (pH 3.5) and 10% glycerol.
Please centrifuge product briefly before opening vial. The dissolved protein can be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
Store at 4°C if entire vial will be used within 4 weeks. Store frozen at -20°C for longer periods of time. For long term storage, it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
