The ELISA kits listed below target RRM2, the symbol for the human gene, ribonucleotide reductase regulatory subunit M2, and a member of the Ribonucleoside diphosphate reductase small chain family. The protein has an enzyme classification of ribonucleoside-diphosphate reductase. The protein encoded by RRM2 has a predicted amino acid length of 389, a mass of 44.9 kDa, and a cytoplasmic subcellular localization. There are currently 2 reported isoforms. RRM2 may also be known by the following names: RR2M, RR2, ribonucleotide reductase small subunit, ribonucleotide reductase small chain, ribonucleotide reductase M2 polypeptide, and ribonucleoside-diphosphate reductase subunit M2. Orthologs of the gene, including human, mouse, and rat are available targets of several ELISA kits.
