Listed are ELISA Kits for the detection of CD39, an alias name of ectonucleoside triphosphate diphosphohydrolase 1. The human protein, encoded by the gene ENTPD1, is 510 amino acid residues long and has a mass of 57,965 daltons. However, there are up to 6 reported isoforms. It is an enzyme of the apyrase class and is a member of the GDA1/CD39 NTPase family. This protein is reported to have a membrane cellular localization, and is glycosylated. The gene is associated with Spastic paraplegia 64, autosomal recessive. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, bovine, chicken, primate, guinea pig, and other mammalian. This target may also be known as: CD39 antigen, ecto-ATP diphosphohydrolase 1, ecto-ATPDase 1, ecto-ATPase 1, lymphoid cell activation antigen, ATPDase, and CD39.
