Anti-OATP1C1 antibodies enable researchers to detect and measure the OATP1C1 antigen in biological samples. This target is a reported synonym of the SLCO1C1 gene, which encodes solute carrier organic anion transporter family member 1C1. This protein is known to function in the transport of ions and transmembrane transport, among other biological roles. The human version of OATP1C1 has a canonical amino acid length of 712 residues and a protein mass of 78.7 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include OATP-F, OATP-RP5, and OATP1.
