The technology of dual-labeled hydrolysis probes (also called TaqMan® real-time PCR probes) exploits the 5 ́-3 ́ exonuclease activity of Taq DNA polymerase to cleave the probe. TaqMan real-time PCR probes are labeled with a fluorescent dye (reporter) at the 5´ end and with a quencher at the 3´ end.
Integrity of DNA/RNA is very important test needed according to the Europe pharmacopeia chapter 5.14.
Mostly the test can be done as agarose gel electrophoresis or using advanced techniques such as PCR or fragment analysis.
All the tests are according to the Europe pharmacopeia test 2.6.21.
To this test belong also plasmid DNA conformation test, because Stability of plasmid DNA depends on its conformation and the right conformation is required (e.g. supercoiled form).
For RNA integrity determination of RIN is important as well.
