Ready-to-use ELISA kits are available for the detection of Ntcp1, an alias of the protein, solute carrier family 10 member 1. The official gene symbol is SLC10A1. The kits can detect several species variants of the protein, including: mouse and rat. The protein, with a mass of 38.1 kDa and length of 349 residues, is reported to be membrane-associated. It is a member of the Bile acid:sodium symporter (BASS) (TC 2.A.28) family and may be known by other names, including: sodium/taurocholate cotransporter, growth-inhibiting protein 29, Na/taurocholate cotransporting polypeptide, Na(+)/taurocholate transport protein, Na(+)/bile acid cotransporter, and sodium/bile acid cotransporter.
