Anti-PCDHA9 antibodies are used in the immunodetection of the protein protocadherin alpha 9. In humans, the canonical protein has a reported length of 950 amino acid residues and a mass of 102.4 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. PCDHA9 is known to be involved with cell adhesion and nervous system development. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include KIAA0345-like 5, PCDH-alpha-9, and PCDH-ALPHA9. PCDHA9 gene orthologs have been reported in the mouse, bovine and chicken species. Some PCDHA9 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Flow Cytometry are also common applications.
