Updated project metadata. HEK293 Flp-In cells were transfected transiently with various SLC22A10 orthologs, including human, chimpanzee, and the mutations to proline or leucine at position 220. After 72 hours of transfection, cell pellets were collected. The quantification was performed on both HEK293 cells and HEK293cells expressing the different SLC22A10 orthologs and mutations
