A number of ELISA Kits are available that target 5'-nucleotidase, ecto (CD73), an alias of the protein, 5'-nucleotidase ecto. The human protein, encoded by the gene NT5E, is an enzyme and member of the 5'-nucleotidase family. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: CALJA, CD73, E5NT, NT, NT5, NTE, eN, eNT. Homology is conserved in other species, such as Mouse, Rat.
