Figure 2

Representative GeneScan tracings for TLR repertoire. Three cases are shown in the upper (a), middle (b), and lower (c) horizontal panels. From left to right, the four vertical columns show β2M (as internal positive control), TLR1, TLR7, and TLR9. All three cases were TLR1+ and TLR7+, but TLR9 varied from being weakly positive (upper panel) to negative (middle panel) to strongly positive (lower panel).
