Introduction
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.
Description
TGF-β 3 Human Recombinant produced in E.Coli is a disulfide-linked homodimeric, non-glycosylated, polypeptide chain containing two 113 amino acid chains and having a total molecular mass of 25.8kDa.
The TGF-β 3 is purified by standard chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered clear solution.
Formulation
The protein solution contains 20% Ethanol and 10mM Acetic acid (AcOH).
Stability
TGF-beta 3 although stable at room temperature for 1 week, should be stored at 4°C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Purity
Greater than 95.0% as determined by SDS-PAGE.

Biological Activity
The activity is determined by the ability to induce chondrogenic differentiation.
Protein content
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 1.718 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
2. Analysis by RP-HPLC, using a calibrated solution of TGF-b 3 as a Reference Standard.
