  • Product overview

    The Human Syndecan-4 Enzyme-Linked Immunosorbent Assay (ELISA) kit (SDC4) (ab213830) is designed for the quantitative measurement of Human Syndecan-4 in cell culture supernatants and serum.

    The ELISA kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for Syndecan-4/SDC4 has been pre-coated onto 96-well plates. Standards (Expression system for standard: NSO; Immunogen sequence: E19-E145) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Syndecan-4/SDC4 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Human Syndecan-4/SDC4 amount of sample captured in plate.

  • Notes

    Syndecan-4 (SDC4) is a protein that in humans is encoded by the SDC4 gene. The protein is found as a homodimer and is a member of the syndecan proteoglycan family. It is mapped to 20q13.12. Syndecan-4 is one of the four vertebrate syndecan’s and has a molecular weight of ~20 kDa. It is a transmembrane (type I) heparan sulfate proteoglycan that functions as a receptor in intracellular signaling. Syndecan-4 also regulates the actin cytoskeleton, cell adhesion, and cell migration. In addition, Syndecan-4 can activate protein kinase C (PKC). The variable domain of syndecan-4 could be a site of self-association. What’s more, Syndecan-4 also binds to phosphatidylinositol (4,5)-bisphosphate (PIP2) through the variable domain and increases PKC activity ten-fold.

  • Research areas

  • Function

    Cell surface proteoglycan that bears heparan sulfate.
  • Tissue specificity

    Expressed in epithelial and fibroblastic cells.
  • 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.
