Anti-SLC4A2 antibodies are used in the immunodetection of the protein solute carrier family 4 member 2. In humans, the canonical protein has a reported length of 1241 amino acid residues and a mass of 137 kDa. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Anion exchanger (TC 2.A.31) protein family, SLC4A2 is known to be involved with the transport of ions and osteoclast differentiation. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include BND3L, EPB3L1, HKB3, NBND3, OPTB9, anion exchange protein 2, anion exchanger 2 type a, and AE2. SLC4A2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of SLC4A2 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
