Anti-PAGE family member 5 antibodies are used for the immunodetection of the protein encoded by the PAGE5 gene. In humans, the canonical protein has a reported length of 130 amino acid residues and a mass of 14 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. It is a member of the GAGE protein family. Other names for this target antigen include P antigen family, member 5 (prostate associated), cancer/testis antigen 16.1, cancer/testis antigen family 16, member 1, cancer/testis antigen family 16, member 2, and P antigen family member 5. Immunohistochemistry is the most common application for the PAGE family member 5 antibodies listed below. ELISA and Western Blot are also common applications.
