Anti-proline rich 4 antibodies are used for the immunodetection of the protein encoded by the PRR4 gene. In humans, the canonical protein has a reported length of 134 amino acid residues and a mass of 15.1 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 2 different isoforms for this protein. It is found to be highly expressed in lacrimal gland where it is found in the acinar cells but not in the intralobular ducts. The proline rich 4 marker can be used to characterize Trachea Serous Cells.* Other names for this target antigen include PROL4, proline-rich protein 4, lacrimal proline-rich protein, nasopharyngeal carcinoma-associated proline-rich protein 4, proline rich 4 (lacrimal), and LPRP. Western Blot is a widely used application for the proline rich 4 antibodies listed below. In addition, ELISA is also a common application.
