Description
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.
Storage & Handling
Lyophilized protein should be stored at -20°C for 1 year. Upon reconstitution, store at 2°C to 8°C for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10%FBS, 5%HSA or 5% trehalose solution), protein aliquots should be stored at -20°C or -80°C for 3-6 months. Avoid repeated freeze/thaw cycles.

Form
Lyophilized
Formulation
The protein was lyophilized from a 0.2 μm filtered solution containing 20 mM sodium citrate, 0.2 M NaCl, pH 3.5. If you have any concerns or special requirements, please confirm with us.
Purity
>98% as determined by SDS-PAGE.
Predicted MW
47.7 kDa
Molecular weight
The protein has a calculated MW of 13.66 kDa. The protein migrates as 15 kDa under reducing condition (SDS-PAGE analysis).
Activity
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.
Endotoxin
<0.01 EU per 1 μg of the protein by the LAL method.

Reconstitution
Centrifuge at 3000 rpm for 5 mins before opening. It is recommended to reconstitute the lyophilized protein in sterile 10 mM HCl to a concentration not less than 100 μg/mL and incubate the stock solution at room temperature for at least 20 mins to ensure sufficient re-dissolved. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
