Anti-PRSS54 antibodies are used in the immunodetection of the protein serine protease 54. In humans, the canonical protein has a reported length of 395 amino acid residues and a mass of 43.8 kDa. It has been described to be a secreted protein. It is notably expressed in the testis. A member of the Peptidase S1 protein family, PRSS54 is known to be involved with proteolysis. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include cancer/testis antigen 67, plasma kallikrein-like protein 4, protease, serine 54, testis tissue sperm-binding protein Li 40a, and inactive serine protease 54. PRSS54 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is a widely used application for the PRSS54 antibodies listed below. In addition, ELISA is also a common application.
