描述（Description）
Transforming growth factor beta 3 ( TGFB3) is also known as TGF-β3, is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including regulates embryogenesis and cell differentiation and is required in various processes such as secondary palate development. TGF-beta 3 is similar with TGF-beta 1 and -beta 2, act as cellular switches to regulate immune function, cell proliferation, and epithelial -mesenchymal transition. TGF-beta-3 is released from LAP by integrins: integrin-binding results in distortion of the LAP chain and subsequent release of the active TGF-beta-3. Once activated following release of LAP, TGF-beta-3 acts by binding to TGF-beta receptors (TGFBR1 and TGFBR2), which transduce signal.
生物活性（Bioactivity）
1.The ED50 is<0.2 ng/mL as measured in a cell proliferation assay using mouse HT-2 cells.
2.Measured by its ability to inhibit the IL-4-dependent proliferation of TF-1 mouse T cells. The ED50 for this effect is 10-80 pg/mL.

制剂（Trait）
Lyophilized from 0.22 μm filtered solution in 50 mM HAC, pH2.8 with trehalose as protectant.Contact us for customized product form or formulation.
复溶（Reconstitution）
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
保存条件&效期（Storage & Stability）
Stored at -20°C for 3 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.Please avoid repeated freeze-thaw cycles.
运输方式(Shipping)
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
生物活性（Bioactivity）
Measured in a cell inhibitionn assay using TF-1 cells at IL4 presence.The ED50 for this effect is ≤0.2 ng/mL. The Bioactivity of F1d0061 was higher than other competing products.
