Prelude™ PreAmp Master Mix (Code No.
Pre-amplification experiments can help increase the initial amount of cDNA or gDNA for specific downstream target sequences.
Application-pre-amplification experiment
The 96-target cell cycle PrimerArray was used to quantify 100 pg cDNA without pre-amplification and 100 pg cDNA after 10 cycles of pre-amplification
Challenges and needs of pre-amplification experiments
When the PCR amplification efficiency of certain target sequences is low, deviations may occur, which may result in insufficient or excessive expression of the target sequence in the pre-amplified sample
▪ Outliers of pre-amplification may get false positives or false negatives
Cost is also a major factor; a single pre-amplification reaction is usually 10-25 times more expensive than standard PCR/qPCR reactions
need:
▪ Unbiased pre-amplification, it is best to amplify as many target sites as possible
How to measure the deviation of pre-amplification experiments?
▪ Comparative experiment between pre-amplified low-initiated cDNA and high-initiated cDNA without pre-amplification
How to measure the deviation of the pre-amplification experiment: Through the ΔCt value obtained in two experiments, calculate the ΔΔCt value and analyze it
Higher sensitivity
Compared with competing companies, cDNA samples have less deviation
Compared with competing companies, FFPE sample deviation is smaller
Use the 162-target breast cancer panel to detect FFPE samples
▪ Use NucleoSpin to extract total RNA in FFPE, and then use PrimeScript RT Master Mix for reverse transcription reaction, followed by 14 cycles of pre-amplification.
In summary, Prelude™ PreAmp Master Mix can perform target-specific pre-amplification of limited or low-quality samples for downstream qPCR, SNP genotyping or TE NGS
▪ High sensitivity, minimum 10 pg starting sample
