The Bioaim Human TGF alpha ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of TGF alpha in human serum and plasma. An antibody specific for human TGF alpha was coated on a 96-well plate. Standards and samples are added to the wells and any TGF alpha present binds to 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 added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of TGF alpha present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Embryogenesis and morphogenesis;

transforming growth factor alpha ( TGF-1 α ) Background: TGF-alpha is a member of the EGF family of cytokines that are synthesized as transmembrane precursors with soluble forms released by proteolytic cleavage. Membrane-bound proTGF-alpha is biologically active and plays a role in mediation of cell-cell adhesion and in juxtacrine stimulation of adjacent cells. Expression of TGF-alpha is widespread in tumors and transformed cells. TGF-alpha is also expressed in normal tissues during embryogenesis and in adult tissues, including pituitary, brain, keratinocytes and macrophages. Considering that TGF-α is a member of the EGF family, the biological actions of TGF-α and EGF are similar. For instance, TGF-α and EGF bind to the same receptor. When TGF-α binds to EGFR it can initiate multiple cell proliferation events. 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.
