Anti-ANP32B antibodies are used in the immunodetection of the protein acidic nuclear phosphoprotein 32 family member B. In humans, the canonical protein has a reported length of 251 amino acid residues and a mass of 28.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is found to be expressed in the heart, lung, pancreas, prostate and in spleen, thymus and placenta. A member of the ANP32 protein family, ANP32B is reported to be a multifunctional protein that is involved in the regulation of many processes including cell proliferation, apoptosis, cell cycle progression or transcription. Synonyms for this target antigen include PHAPI2, SSP29, acidic leucine-rich nuclear phosphoprotein 32 family member B, acidic (leucine-rich) nuclear phosphoprotein 32 family, member B, and APRIL. A number of ANP32B 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.
