A number of ELISA Kits are available that target nitric oxide synthase 3 (endothelial cell), an alias of the protein, nitric oxide synthase 3. The human protein, encoded by the gene NOS3, is an enzyme and member of the NOS family. The protein's cellular localization is indicated to be cytoplasmic and membrane-associated. Additional synonyms or past names for this protein may include: ECNOS, eNOS. Homology is conserved in other species, such as Mouse, Rat, Frog.
