| 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. | | | Catalog # | T8250-45L | | TGF-b3 Mouse Recombinant produced in E. coli is a disulfide-linked homodimeric, non-glycosylated, polypeptide chain containing 112 amino acids and having a molecular mass of 25,445 Dalton. | | The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Leu-Asp-Thr-Asn. | | Biological Activity | The ED50 as determined by the cell toxicity assay using the WHO Standard 98/608 as a direct comparison is < 0.05ng/ml corresponding to a specific activity of 20,000,000 Units/mg. | | Storage and Stability | May be stored at 4°C. For long-term storage, aliquot and store at 4°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Do not freeze. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer. | | | | | | Molecular Weight | 25.445kD | | Source | E. coli | | Form | Supplied as a liquid in 20% ethanol and 0.12% acetic acid. | | Purity | 98% (SDS-PAGE) |
