The APX ELISA kits listed below utilize specific antibodies for the plate-based assay of APX in various samples. APX is another term for the APEX1 gene, which encodes the protein, apurinic/apyrimidinic endodeoxyribonuclease 1 in humans. It has been reported that APX plays a role in pathways of aging, among other functions. Structurally, the APEX1 protein is described to be 318 amino acid residues in length and 35.6 kilodaltons in mass. It is localized to the nucleus, ER, and cytoplasm of the cell. This protein is known to be ubiquitinated, acetylated, cleaved and phosphorylated. Other names for this target antigen include APE, APE1, and APEN.
