The ELISA kits listed below target XRCC4, the symbol for the human gene, X-ray repair cross complementing 4, and a member of the XRCC4 family. The protein encoded by XRCC4 has a predicted amino acid length of 336, a mass of 38.3 kDa, and a nuclear subcellular localization. There are currently 3 reported isoforms. Pathologic involvement is reported in Short stature, microcephaly, and endocrine dysfunction. XRCC4 may also be known by the following names: SSMED, X-ray repair complementing defective repair in Chinese hamster cells 4, and DNA repair protein XRCC4. Orthologs of the gene, including human and mouse are available targets of several ELISA kits.
