Anti-solute carrier family 4 (sodium bicarbonate cotransporter), member 5 antibodies enable researchers to detect and measure the solute carrier family 4 (sodium bicarbonate cotransporter), member 5 antigen in biological samples. This target is a reported synonym of the SLC4A5 gene, which encodes solute carrier family 4 member 5. This protein is known to function in the regulation of gene expression and eye development, among other biological roles. The human version of solute carrier family 4 (sodium bicarbonate cotransporter), member 5 has a canonical amino acid length of 1137 residues and a protein mass of 126.3 kilodaltons, although 8 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include electrogenic sodium bicarbonate cotransporter 4 and solute carrier family 4 (sodium bicarbonate cotransporter), member 5.
