Anti-SLC21A12 antibodies are used in antigen-specific immunodetection in biological samples. The target SLC21A12 is a known alias name of the protein solute carrier organic anion transporter family member 4A1, encoded by the SLCO4A1 gene in humans. This 722-amino acid residue protein is known to mediate the Na(+)-independent transport of organic anions such as the thyroid hormones T3 (triiodo-L-thyronine), T4 (thyroxine) and rT3, taurocholate, estrone 3-sulfate, estradiol-17beta-glucuronide and prostaglandin E2 (PGE2). It is localized to the cell membrane of the cell and features glycosylated post-translational modifications. In terms of tissue expression, it is found to be widely expressed, with the exception of spleen and leukocytes.
