Transforming Growth Factor beta 3 (TGF beta 3) is a member of the TGF beta family of growth factors. The TGF beta polypeptides are multifunctional, capable of influencing cell proliferation, differentiation, and other functions in a wide range of cell types. The multi-modal nature of TGF beta is seen in its ability to stimulate or inhibit cellular proliferation. In general, cells of mesenchymal origin appear to be stimulated by TGF beta whereas cells of epithelial or neuroectodermal origin are inhibited by the peptide

Figure 1: TGF-β3 inhibits the mIL-4-dependent 3H-thymidine incorporation by HT-2 cells in a dose-dependent manner (Tsang, M. et al., 1995, Cytokine 7:389). The ED50 for this effect is typically 0.01 - 0.03 ng/mL.

Figure 2: To measure the ability of the antibody to neutralize the bioactivity of TGF-β3 on HT-2 cells, rhTGF-β3 was incubated with various concentrations of the antibody for 1 hour at room temperature in a 96 well microtiter plate. Following this preincubation period, HT-2 cells were added. The assay mixture in a total volume of 100 μL/well, containing antibody at the concentrations indicated, rmIL-4 at a concentration of 7.5 ng/mL, rhTGF-β3 at a concentration of 0.1 ng/mL, and cells at 1 x 105 cells/mL, was incubated at 37° C for 48 hours in a humidified incubator. 3H-thymidine was added during the final four hours. The cells were subsequently harvested onto glass fiber filters and the 3H-thymidine incorporated into DNA was determined. The ND50 of the antibody, under these conditions, is approximately 0.005 - 0.015 μg/mL.
