Abstract: Molecular research and therapy relies heavily on tests utilizing
polymerase chain reaction (PCR) and in vitro transcription
(IVT) technologies. PCR enables sensitive detection, specific
identification, and accurate quantification of nucleic acid
sequences and IVT is used to manufacture mRNA. To avoid
false positives and uncertainty in the assay results, it is crucial
that the reagents used in PCR and IVT applications be free of
foreign contaminants, such as DNA, RNA, HCP, endotoxins
originating from the manufacturing environment, human
operator, cross-contamination from shared equipment, or host
cells expressing recombinant proteins. To remove the risk of
these types of contamination, Thermo Fisher Scientific has
developed and implemented a new process for manufacturing
such enzymes. We use a closed system based on single-use
technology to drastically minimize the risk of contamination
inherent to the conventional manufacturing process. To help
ensure conformance to strict purity requirements, we subject
our DNA-free PCR reagents and IVT enzymes to stringent
quality tests. This combination of manufacturing systems and
quality testing delivers PCR reagents that are orders of
magnitude cleaner than other “DNA-free” reagents on the
market and IVT reagents that meet all quality and regulatory
requirements for therapeutic use.
Summary: Conventional PCR and IVT reagents, which have been shown
to contain contaminating DNA/RNA, fall short of being able to
provide the reliability required to detect low abundance
DNA/RNA targets. To support developers of DNA based assay
and IVT kits, Thermo Fisher Scientific is the first to offer
DNA/RNA-free PCR and IVT reagents manufactured using a
closed single-use system technology.
