The HepG2-2B1 cell clone showed more stable and higher levels of NTCP expression (Figure 1(D)) and PreS1-peptide binding capability (Figure 1(C)), which possibly contributed to its better infection performance than that of the other clones, particularly in cells infected with a low-MOI HBV inoculum (Figure 1(E and F)). This evidence concerns the gene SLC10A1 and infection.
