Anti-Aquaporin 2 (AQP2) [K5007] Antibody

This rabbit polyclonal antibody was generate against a peptide sequence corresponding to the C-terminal region of Aquaporin 2 (AQP2) and reacts with human, mouse, and rat AQP2.

Highlights:

  • Reacts with human, mouse, and rat AQP2
  • Antibody recognizes both unphosphorylated and phosphorylated forms ofAQP2
  • Peptide sequence (aa 237-255) upstream from polyphosphorylated region
  • Suitable for Western Blot and Immunocytochemistry applications

Aquaporins, also known as water channels, form pores in cell membranes and selectively transport water in and out of the cell. Aquaporins are involved in regulation of water balance and blood pressure, and thirteen different isoforms have been found in mammals. Aquaporin 2 (AQP2) is located in the collecting duct of the kidney, and is regulated by the peptide hormone vasopressin. AQP2 expression is increased in conditions where there is water retention, such as pregnancy and congestive heart failure, and mutations of AQP2 are associated with nephrogenic diabetes insipidus. Also, lithium treatment, often administered for bipolar disorder, can cause acquired diabetes insipidus by decreasing AQP2 expression.
