Anti-CACT antibodies are used in antigen-specific immunodetection in biological samples. The target CACT is a known alias name of the protein solute carrier family 25 member 20, encoded by the SLC25A20 gene in humans. This 301-amino acid residue protein 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. It is localized to the mitochondria of the cell. It is reported to be expressed in many tissues, such as the duodenum and liver. The term CAC is another synonym for CACT. Indicated applications for CACT antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
