Aquaporin 2 (AQP2) is a membrane protein involved in plasma membrane water transport in the renal collecting duct. This antibody is targeted to a peptide sequence upstream from the phosphorylated region that, upon phosphorylation, can diminish the antibody signal in immunoblots and immunocytochemistry.

FAQs for Aquaporin-2 Antibody (NB110-74682). (Showing 1 - 2 of 2 FAQs).

  1. We have a customer who is interested in catalog # NB110-74682, but he needs more information regarding the sequence if possible. The range of 200-300 covers both a predicted helical and cytoplasmic domain. Would it be possible to know if the exact sequence is contained entirely within either of these domains? He is hoping for the helical as he needs to detect on the cell surface.
    • Unfortunately for your customer, NB110-74682 recognizes the cytoplasmic domain.
  2. I have a customer who is interested in antibody NB100-74682 anti-Aquaporin. They are concerned about the fact that there are only a few extracellular amino acids in the region 200-300 of AQP2. Please see below. The immunogen for anti-AQP2 is listed as aa 200 - 300 of aquaporin 2. This product is listed as having application in ICC, which requires an extracellular epitope. From looking at the structure of Aquaporin 2, it appears that only about 4 residues of aa200 - 300 are extracellular. Can you explain this? Do you know if the cells were permeabilized for the ICC image shown on your datasheet or was the antibody able to cross the membrane efficiently enough to stain without permeabilizing the cells?
    • Our immunogen for NB110-74682 is to the cytoplasmic domain of AQP2. Furthermore, your customer is incorrect that ICC requires and extracellular domain, as many antibodies that recognize an intracellular target work quite well for ICC when the cells are permeabilized. We permeabilize for all of our ICC testing and this antibody certainly requires it.
