  • Product overview

    Abcam’s Syndecan-1 (CD138) Human in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Syndecan-1 in Human serum, plasma, buffered solutions and supernatants.

    A monoclonal antibody specific for Syndecan-1 has been coated onto the wells of the microtiter strips provided. Samples, including standards of known Syndecan-1 concentrations, control specimens or unknowns are pipetted into these wells. During the first incubation, the standards or samples and a biotinylated monoclonal antibody specific for Syndecan-1 are simultaneously incubated. After washing, the enzyme Streptavidin-HRP, that binds the biotinylated antibody is added, incubated and washed. A TMB substrate solution is added which acts on the bound enzyme to induce a colored reaction product. The intensity of this colored product is directly proportional to the concentration of Syndecan-1 present in the samples.

    This kit will recognize both endogenous and recombinant Human Syndecan-1.

  • Tested applications
    Suitable for: Sandwich ELISAmore details
  • Platform


  • Function
    Cell surface proteoglycan that bears both heparan sulfate and chondroitin sulfate and that links the cytoskeleton to the interstitial matrix.
  • Sequence similarities
    Belongs to the syndecan proteoglycan family.
  • Post-translational
    Shedding is enhanced by a number of factors such as heparanase, thrombin or EGF. Also by stress and wound healing. PMA-mediated shedding is inhibited by TIMP3.
  • Cellular localization
    Membrane. Secreted. Shedding of the ectodomain produces a soluble form.

  • Syndecan measured in undiluted cell culture supernatants, including the positive control from kit (duplicates +/- SD).

  • Syndecan measured in human biological fluids (dilution range 1/1-1/10); mouse and pig samples (plasma and serum) were below limit of detection (duplicates +/- SD).

  • Standard curve of human syndecan with background signal subtracted (duplicates; +/- SD).

Thank you for contacting us.

In order to measure syndecan-1 from cell culture supernatants, spinning at 1000g during 10 minutes is necessary to remove particulates and aggregates.
