Human Recombinant TGF-alpha
Transforming growth factor alpha
概要
Transforming growth factor-alpha (TGF-α) a member of the epidermal growth factor (EGF) family that is expressed in normal epithelial cells, monocytes, macrophages, brain cells, keratinocytes, and cancer cells. TGF-α binds EGF receptor (EGFR) and activates tyrosine kinase signaling. In epidermal and epithelial cells, this results in proliferation and differentiation. TGF-α is not structurally or genetically related to TGF-β, and the two ligands act through different signaling pathways. In vitro, TGF-α was shown to stimulate anchorage-independent growth (Singh & Coffey).

Data
(A) The biological activity of Human Recombinant TGF-alpha was tested by its ability to promote the proliferation of BALB/c 3T3 cells. Cell proliferation was measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the above example is less than 0.2 ng/mL. (B) 2 μg of Human Recombinant TGF-alpha was resolved with SDS-PAGE under reducing (+) conditions and visualized by Coomassie Blue staining.
