Anti-PPAN antibodies are used in the immunodetection of the protein peter pan homolog. In humans, the canonical protein has a reported length of 473 amino acid residues and a mass of 53.2 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is widely expressed across many tissue types. PPAN is suspected to have a role in cell growth. Synonyms for this target antigen include brix domain-containing protein 3, homolog of S. cerevisiae SSF1, second-step splicing factor 1, suppressor of sterile four 1, and suppressor of SWI4 1 homolog. PPAN gene orthologs have been reported in the frog and zebrafish species. A number of PPAN antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
