Species of Origin
His Tag (C-term)
Lyophilized from a 0.2 µm filtered solution containing 20 mM sodium citrate and 0.2 M NaCl, pH 3.5.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 13.66 kDa.
The protein migrates as 15 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to inhibit IL-4-induce proliferation in HT-2 cells. The ED₅₀ for this effect is <0.2 ng/mL. The specific activity of recombinant human TGF beta 2 is > 5 x 10⁶ IU/mg.
<0.01 EU per 1 µg of the protein by the LAL method.
Transforming Growth Factors beta 2 (TGFβ-2) is a 12.85 kDa member of the epidermal Growth Factors with 113 amino acid residues. TGFβ-2 is expressed from throughout the body. TGFβ-2 is a regulator of cell proliferation, differentiation, apoptosis, cell plasticity and migration, etc. TGF-β-2 also associates with various kinds of diseases, such as cancer and tissue fibrosis.

It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved. In some experiments, it recommends to add 10 mM HCl when reconstitute lyophilized protein.
The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.
