Anti-SRPX2 antibodies are used in the immunodetection of the protein sushi repeat containing protein X-linked 2. In humans, the canonical protein has a reported length of 465 amino acid residues and a mass of 53 kDa. Its subcellular localization is in the cytoplasm and is secreted. It is reported to be expressed in neurons of the rolandic area of the brain. SRPX2 is known to act as a ligand for the urokinase plasminogen activator surface receptor. The SRPX2 gene has been associated with the disease, Rolandic epilepsy, impaired intellectual development, and speech dyspraxia, X-linked. Synonyms for this target antigen include CBPS, PMGX, RESDX, SRPUL, sushi repeat-containing protein SRPX2, and BPP. SRPX2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SRPX2 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
