SLC10A1 and lymphoma: To prepare immunizing antigens and reagents for antibody screening by flow cytometry, we transduced Daudi lymphoma and HepG2 cell lines with a cDNA encoding human NTCP in a retroviral vector (31) and established Daudi-NTCP and HepG2-NTCP cell lines that both expressed NTCP on the cell surface and bound preS1 at significant levels (data not shown).
