Swine recombinant TGF beta 1 (Transforming growth factor beta 1) protein, AF

About this product

Transforming Growth Factors beta 1 (TGF beta 1) is the cytokine of the TGF-beta family, which is a 12.5 kDa protein containing 113 amino acid residues. TGF beta 1 is produced by white blood cell which plays an important role in inflammation, cell proliferation and differentiation. TGF beta 1 also has several functions about cancer and auto-immune diseases. TGF-beta 1 not only can activate the smad signaling but also can induce the MAPK, Rhoa and RAS.

Applications

Cell Culture

Purification

>98% as determined by SDS-PAGE.

Endotoxin

<0.1 EU per 1 μg of the protein by the LAL method.

Bioactivity

Measure by its ability to inhibit IL-4-induce proliferation in HT-2 cells. The ED50 for this effect is <0.1 ng/mL.

Form

The protein was lyophilized from a 0.2 μm filtered solution containing 20 mM sodium citrate, 0.2 M NaCl, pH 4.5. If you have any concerns or special requirements, please confirm with us.

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.

Molecular Weight

The protein has a calculated MW of 13.73 kDa. The protein migrates as 11-17 kDa under reducing condition (SDS-PAGE analysis) .

Storage Conditions

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.
