Ready-to-use ELISA kits are available for the detection of primase and polymerase (DNA-directed), an alias of the protein, primase and DNA directed polymerase. The official gene symbol is PRIMPOL. The protein, with a mass of 64.4 kDa and length of 560 residues, is reported to be nuclear and mitochondrial. It is a member of the Eukaryotic-type primase small subunit family and may be known by other names, including: Primpol1, CCDC111, hPrimpol1, coiled-coil domain-containing protein 111, and DNA-directed primase/polymerase protein.
