Anti-PRX-4 antibodies enable researchers to detect and measure the PRX-4 antigen in biological samples. This target is a reported synonym of the PRDX4 gene, which encodes peroxiredoxin 4. This protein is known to function in extracellular matrix organization and male gonad development, among other biological roles. The human version of PRX-4 has a canonical amino acid length of 271 residues and a protein mass of 30.5 kilodaltons. It is reported to be localized in the ER and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include AOE37-2, AOE372, and HEL-S-97n.
