Anti-solute carrier family 25 (mitochondrial carrier; ornithine transporter) member 2 antibodies are used in antigen-specific immunodetection in biological samples. The target solute carrier family 25 (mitochondrial carrier; ornithine transporter) member 2 is a known alias name of the protein solute carrier family 25 member 2, encoded by the SLC25A2 gene in humans. This 301-amino acid residue protein is reported to be a mitochondrial transporter of the positively charged amino acids ornithine, lysine and arginine, and the neutral amino acid citrulline. It is localized to the mitochondria of the cell. In terms of tissue expression, it is reported to be expressed in the liver, testis, spleen, lung, pancreas, and small intestine and expressed poorly in other tissues. Other synonyms for solute carrier family 25 (mitochondrial carrier; ornithine transporter) member 2 include mitochondrial ornithine transporter 2 and solute carrier family 25 (mitochondrial carrier; ornithine transporter) member 2.
