  • Product overview

    The Human Stanniocalcin 2 / STC-2 ELISA (Enzyme-Linked Immunosorbent Assay) kit (ab222880) is designed for detection of Stanniocalcin 2 / STC-2 in human plasma, serum, and cell culture samples.

    This assay employs a quantitative sandwich enzyme immunoassay technique that measures human Stanniocalcin 2 / STC-2 in approximately 4 hours. A polyclonal antibody specific for human Stanniocalcin 2 / STC-2 has been pre-coated onto a 96-well microplate with removable strips. Stanniocalcin 2 / STC-2 in standards and samples is sandwiched by the immobilized antibody and a biotinylated polyclonal antibody specific for human Stanniocalcin 2 / STC-2, which is recognized by a streptavidin-peroxidase (SP) conjugate. All unbound material is washed away and a peroxidase enzyme substrate is added. The color development is stopped and the intensity of the color is measured.

    The entire kit may be stored at -20°C for long term storage before reconstitution - Avoid repeated freeze-thaw cycles.

  • Notes

    Stanniocalcin 2 / STC-2, also known as stanniocalcin-related protein, is a secreted homodimeric glycoprotein that belongs to the stanniocalcin family. Stanniocalcin 2 / STC-2 contains 302 amino acid residues with 34% STC-1 identity and a molecular mass of 32 kDa. The N terminus of Stanniocalcin 2 / STC-2 contains a signal peptide followed by a cysteine-rich region that may mediate homodimerization. In the kidney, the function of Stanniocalcin 2 / STC-2 on phosphate transport appears to be the opposite to that of STC-1. Stanniocalcin 2 / STC-2 is phosphorylated by casein kinase-2 on serine residues and can inhibit phosphorylation of cell-surface proteins. It is expressed in a wide variety of tissues, including the pancreas, skeletal muscle, and small intestine. Stanniocalcin 2 / STC-2 may play a role in the regulation of renal and intestinal calcium and phosphate transport, cell metabolism, and cellular calcium/phosphate homeostasis.
