Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

TGFA (Transforming growth factor alpha) is a protein that is a member of the epidermal growth factor (EGF) family; TGF-α is a mitogenic polypeptide. The protein becomes activated when binding to receptors capable of protein kinase activity for cellular signaling. TGF-α is a transforming growth factor that is a ligand for the epidermal growth factor receptor, which activates a signaling pathway for cell proliferation, differentiation and development. TGF-α may act as either a transmembrane-bound ligand or a soluble ligand. It has been associated with many types of cancers, and it may also be involved in some cases of cleft lip/palate. TGF-α can be produced in macrophages, brain cells, and keratinocytes. TGF-α induces epithelial development. Cell proliferation events that involve TGF-α bound to EGFR include wound healing and embryogenesis. TGF-α is also involved in tumerogenesis and believed to promote angiogenesis. TGFα has also been shown to stimulate neural cell proliferation in the adult injured brain. Diseases associated with TGFA include bronchiolo-alveolar adenocarcinoma and bone marrow necrosis.
