Anti-SLC25A20 antibodies are used in the immunodetection of the protein solute carrier family 25 member 20. In humans, the canonical protein has a reported length of 301 amino acid residues and a mass of 32.9 kDa. Its subcellular localization is in the mitochondria. It is notably expressed in many tissues, such as the duodenum and liver. A member of the Mitochondrial carrier (TC 2.A.29) protein family, SLC25A20 is known to mediate the electroneutral exchange of acylcarnitines (O-acyl-(R)-carnitine or L-acylcarnitine) of different acyl chain lengths (ranging from O-acetyl-(R)-carnitine to long-chain O-acyl-(R)-carnitines) with free carnitine ((R)-carnitine or L-carnitine) across the mitochondrial inner membrane, via a ping-pong mechanism. Synonyms for this target antigen include CACT, mitochondrial carnitine/acylcarnitine carrier protein, solute carrier family 25 (carnitine/acylcarnitine translocase), member 20, and CAC. A number of SLC25A20 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
