What is the difference between Positive PCR Control (PPC) and Microbial DNA Positive Control?

Positive PCR Control (PPC) is used to test for the presence of inhibitors in the sample or the efficiency of the polymerase chain reaction itself using a pre-dispensed artificial DNA sequence and the primer set that detects it. Microbial DNA Positive Control is a mixture of synthetic oligonucleotides that are targets for each primer/hydrolysis probe set. It is used to test that each Microbial DNA qPCR Assay is performing correctly.
