Tumor growth factor alpha (TGF-α) is a member of the epidermal growth factor (EGF) family. TGF-α function is mediated through binding the EGF receptor (EGFR) to activate receptor tyrosine kinase signaling. TGF-α functions as a mitogen to activate epithelial cell proliferation, growth, and differentiation. In the gastric mucosa, TGF-α production inhibits gastric acid secretion and therefore plays a central role in the pathogenesis of the stomach disease. TGF-α is also produced in adult macrophages, brain cells, keratinocytes, and is widely expressed in cancer cells.Activity Assay
Human TGF-α (Animal-Free) is fully biologically active when compared to standard. The activity is determined by the ability to induce 3T3 cells proliferation and it is typically less than 2 ng/ml. This corresponds to an expected specific activity higher than 5 x 105 units/mg.AA Sequence
