Size markers are shown in red. A: Original primer sets. This sample was designated as reactive due to polyclonal amplification using the TCRγ primer sets. Primer set 7 is shown (blue). B: Final primer sets. Clonal product detected using one of the TCRγ primer sets added in the final protocol (primer set 10; green). V2&6, Jx-2, V3&5&7 and Jx-1 refer to the TCRγ V and J segments amplified by the primer set (see Table 3).
