Anti-BPIFA3 antibodies are used in the immunodetection of the protein BPI fold containing family A member 3. In humans, the canonical protein has a reported length of 254 amino acid residues and a mass of 28.4 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis. It is a member of the Plunc protein family. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include short long palate, lung and nasal epithelium carcinoma associated 3. BPIFA3 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. These BPIFA3 antibodies are widely used in Western Blot experiments, among other applications.
