Anti-pr1/Pr2 antibodies are used in antigen-specific immunodetection in biological samples. The target pr1/Pr2 is a known alias name of the protein proline rich protein HaeIII subfamily 2, encoded by the PRH2 gene in humans. Other synonyms for pr1/Pr2 include PRP-1/PRP-2, Pr, and pr1/Pr2. Some pr1/Pr2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
