Anti-FOLT antibodies enable researchers to detect and measure the FOLT antigen in biological samples. This target is a reported synonym of the SLC19A1 gene, which encodes solute carrier family 19 member 1. This protein is known to function in the transport of ions, among other biological roles. The human version of FOLT has a canonical amino acid length of 591 residues and a protein mass of 64.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the placenta, duodenum, cerebral cortex, and cerebellum. This target antigen may also be known as CHMD.
