  • Product overview

    Thrombospondin 1 Human ELISA Kit (ab193716) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human Thrombospondin 1 in serum, plasma and cell culture supernatants.

    This assay employs an antibody specific for Human Thrombospondin 1 coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures Thrombospondin 1 present in the samples. The wells are washed and biotinylated Human Thrombospondin 1 antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of Thrombospondin 1 bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Function
    Adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. Binds heparin. May play a role in dentinogenesis and/or maintenance of dentin and dental pulp (By similarity). Ligand for CD36 mediating antiangiogenic properties. Plays a role in ER stress response, via its interaction with the activating transcription factor 6 alpha (ATF6) which produces adaptive ER stress response factors.
