Impact of dNTP reagents on GeneScan profiles. TRG-1T-2F PCR assay profiles of sample DE-191 (T-LGL), analyzed in 3 laboratories (A, B and C) using the same PCR conditions, except for the dNTP source. Laboratories B and C used the same dNTP reagents resulting in a single peak, while laboratory A used dNTP reagents from a different provider (ThermoFischer), with the PCR profile displaying 2 clonal peaks.
