Ready-to-use ELISA kits are available for the detection of 5'-NT, an alias of the protein, 5'-nucleotidase ecto. The official gene symbol is NT5E. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian. The protein, with a mass of 63.4 kDa and length of 574 residues, is reported to be membrane-associated. It is a member of the 5'-nucleotidase family and may be known by other names, including: eN, E5NT, CALJA, ecto-5'-nucleotidase, Purine 5-Prime-Nucleotidase, and 5'-nucleotidase.
