A number of ELISA Kits are available that target polymerase (DNA directed), delta 2, regulatory subunit, an alias of the protein, DNA polymerase delta 2, accessory subunit. The human protein, encoded by the gene POLD2, is an enzyme and member of the DNA polymerase delta/II small subunit family. The protein's cellular localization is indicated to be nuclear. Homology is conserved in other species, such as Mouse, Rat, Arabidopsis, Zebrafish, Frog, Chicken.
