Figure 2: Post-PCR polyacrylamide gel analysis using the TRAPeze (Serologicals Corporation) confirms the typical ladder of products and amplification of the internal control (IC). 293T cells were evaluated as positive control and inactivated 293T samples served as negative control. Samples marked with an asterisk displayed absence of IC amplification in the TeloTAGGG PCR ELISAPLUS (Roche Diagnostics).
