Table 3. Inhibition studies to test the co-purification of PCR inhibitors.

Two different concentrations of IC DNA were used as the DNA template in the qPCR reactions to test the co-purification of PCR inhibitors in samples extracted from whole blood using ME or EZ methods; High DNA concentration or Low DNA concentration. Control experiments did not contain genomic DNA in the reaction. Each column shows the method which the genomic DNA present [or not for the controls] was extracted [ME or EZ] and amount of IC plasmid present [High or Low].
