| Description | TGFB1 is the prototype member of the TGF-beta super-family that includes Inhibins, Activin A, MIS (M?llerian inhibiting substance), BMP (bone morphogenetic proteins), dpp (decapentaplegic) and Vg-1. TGFB1 is the most potent known growth inhibitor for normal and transformed epithelial cells, endothelial cells, fibroblasts, neuronal cells, lymphoid cells and other hematopoietic cell types. TGF-beta inhibits the proliferation of T lymphocytes by down-regulating predominantly IL2 mediated proliferative signals and also inhibits the growth of natural killer cells. Recombinant human TGFB1 is a disulfide linked homodimer protein that migrates at approximately 26kDa under non-reducing conditions. |
| Accession | P01137 |
| Functions | The ED50 as determined by the ability to inhibit the proliferation of mink lung epithelial cells was found to be in the range of 0.05-0.1 ng/ml |
| Formulation | Lyophilized from 0.2 ?m filtered PBS solution pH 7.4 |
| Solubility | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers. |
