Description : |
Transforming growth factor beta 3(TGF β3) is one of three closely related mammalian members of the large TGF β superfamily, TGF-β1, β2, and β3, signal through the same receptor and elicit similar biological responses. The mammalian TGF-β3 controls a vast array of biological processes including immune regulation, cell proliferation, epithelial-mesenchymal transition, and the bone formation. It is generally recognized to facilitate chondrogenic differentiation of precursor cells. It may also have a dose-dependent inhibitory effect on osteogenesis. |
Bio-activity : |
The activity was measured by its ability to inhibit the IL-4 induced proliferation in mouse HT-2 cells (BALB/c spleen activated by sheep erythrocytes in the presence of IL-2). |
Molecular Mass : |
25 kDa |
Endotoxin : |
<0.5 EU/ μg |
Purity : |
High Purity, >95% by SDS-PAGE |
Stability : |
Use a manual defrost freezer and avoid repeated freeze-thaw cycles. In general: 12 months from date of receipt, -20 to -80 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -80 centigrade under sterile conditions after reconstitution. |
Storage Buffer : |
Lyophilized from a 0.2 μm filtered solution in PBS without carrier protein |
Reconstitution : |
Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile 4 mM HCl containing at least 0.1% human or bovine serum albumin. |
