Anti-SFRP5 antibodies are used in the immunodetection of the protein secreted frizzled related protein 5. In humans, the canonical protein has a reported length of 317 amino acid residues and a mass of 35.6 kDa. It has been described to be a secreted protein. It is reported to be highly expressed in the retinal pigment epithelium (RPE) and pancreas. A member of the Secreted frizzled-related protein (sFRP) protein family, SFRP5 is known to be involved with the morphogenesis of anatomical structure and the apoptotic pathway. Synonyms for this target antigen include FRP-1b, SARP-3, frizzled-related protein 1b, secreted apoptosis related protein 3, and SARP3. SFRP5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SFRP5 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
