Anti-PRSS56 antibodies are used in the immunodetection of the protein serine protease 56. In humans, the canonical protein has a reported length of 603 amino acid residues and a mass of 64.6 kDa. It is noted to be expressed neural retina, cornea, sclera and optic nerve. A member of the Peptidase S1 protein family, PRSS56 is known to be a serine protease required during eye development. Post-translational modifications have been described, including glycosylation. The PRSS56 gene has been associated with the disease, Microphthalmia. Synonyms for this target antigen include protease, serine 56 and putative serine protease 56. PRSS56 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunofluorescence is the most common application for the PRSS56 antibodies listed below. ELISA, Western Blot, and Immunocytochemistry are also common applications.
