Product Overview
This rabbit polyclonal antibody detects stanniocalcin-2 (gene STC2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 33.2 kDa, and the supplier reports an observed band at about 33 kDa.
Stanniocalcin-2 (STC2) is a secreted glycoprotein related to stanniocalcin-1 that affects calcium and phosphate homeostasis. It is induced by cellular stress and hypoxia, is known to inhibit the protease PAPP-A and thereby influence IGF signaling and growth, and is studied in metabolism and cancer.
