ELISA 1/20000.


  • FunctionProduces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway. NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets.
  • Tissue specificityPlatelets, placenta, liver and kidney.
  • Sequence similaritiesBelongs to the NOS family.
    Contains 1 FAD-binding FR-type domain.
    Contains 1 flavodoxin-like domain.
  • Cellular localizationCell membrane. Membrane > caveola. Cytoplasm > cytoskeleton. Golgi apparatus. Specifically associates with actin cytoskeleton in the G2 phase of the cell cycle and which is favored by interaction with NOSIP and results in a reduced enzymatic activity.

Thank you for your patience. I managed to locate a publication that used endothelia from aorta of rats for an eNOS (phospho S1176) experiment. Therefore, this can also be used as a positive control for ab51038. Please see the Materials and Meth...

Thank you for your enquiry. I can see from the SwissProt database entry for this protein (http://us.expasy.org/cgi-bin/niceprot.pl?P29474) that they list amino acid 1177 as being a phosphoserine. If you look at the sequence, however, they are incl...
