Proof of concept for recombinant cellular controls in quantitative molecular pathogen detection.


ABSTRACT: In this study, we present the concept of internal sample process controls (ISPCs) to monitor the efficiency of an analytical chain using sample preparation and quantitative PCR (qPCR). A recombinant Listeria monocytogenes ?prfA (targeted deletion) strain containing a competitive artificial single-copy genomic target was applied to naturally contaminated samples to demonstrate its analytical suitability as an ISPC.

In this study, we present the concept of internal sample process controls (ISPCs) to monitor the efficiency of an analytical chain using sample preparation and quantitative PCR (qPCR). A recombinant Listeria monocytogenes ΔprfA (targeted deletion) strain containing a competitive artificial single-copy genomic target was applied to naturally contaminated samples to demonstrate its analytical suitability as an ISPC. ...[more]
