TGF Alpha ELISA Kit (Transforming Growth Factor Alpha)

INTENDED USE

Human TGF alpha ELISA kit is a reliable quantitative procedure for measuring transforming growth factor alpha (TGF alpha, TGF-a, TGF-α, TGF-alpha) in human tissue homogentaes, plasma, serum and other biological fluids. This assay has a minimum sensitivity detection limit of 9.375 pg/ml.

BACKGROUND

Transforming growth factor alpha (TGF alpha, TNF-alpha) is a protein that is encoded by the TGFA gene in humans. It is produced in; brain cells, keratinocytes and macrophages. It is a mitogenic polypeptide belonging to the epidermal growth factor (EGF) family. This protein can be activated upon binding of epidermal growth factor receptors, these are capable of protein kinase activity and activating cell signalling pathways for cellular proliferation, differentiation and development.

There is also evidence to suggest that  TGF alpha can stimulate the proliferation of neural cell in the adult injured brain. It can also promote angiogenesis and is involved in tumerogenesis. The 50-amino acid protein is believed to be the bioactive molecule that is produced and secreted by many tumor cell lines.
