  • Product overview

    Abcam’s TGF alpha Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human TGF alpha in serum, plasma, cell culture supernatants

    This assay employs an antibody specific for Human TGF alpha coated on a 96-well plate. Standards and samples are pipetted into the wells and TGF alpha present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human TGF alpha antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of TGF alpha bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Relevance
    Transforming growth factor alpha (TGF alpha) is an acid- and heat-stable originally discovered in rodents and humans. TGF alpha protien is 33% homologous to epidermal growth factor (EGF). TGF alpha binds to the EGF receptor, mediating tyrosine phosphorylation of the receptor, and promotes anchorage-independent growth of normal rat fibroblasts in soft agar in the presence of transforming growth factor-beta. TGF alpha is secreted by a variety of transformed cells and tumors, embryonic cells and some normal adult cells . TGF alpha bioactivity has also been found in the urine of cancer patients. It has been suggested that it may act as an autocrine growth factor for the induction or maintenance of malignancy.
