  • Product overview

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

    This assay employs an antibody specific for Osteopontin coated on a 96-well plate. Standards and samples are pipetted into the wells and Osteopontin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Mouse Osteopontin 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 Osteopontin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • PlatformMicroplate


  • FunctionBinds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction.
    Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity.
  • Tissue specificityBone. Found in plasma.
  • Sequence similaritiesBelongs to the osteopontin family.
  • Post-translational
    Extensively phosphorylated on clustered serine residues.
    N- and O-glycosylated.
    Phosphorylation sites are present in the extracelllular medium.

Thank you for contacting us.

The mouse OPN kit does have a very low level cross-reactivity with human OPN. We’ve measure it to around 2-3% cross-reactivity. This is low enough I think you could measure it in your sample, but you might ne...
