Understanding Reverse Transcriptase — Effects on Ct value
The reverse transcription step is one of the greatest sources of variation in RT-qPCR. With SuperScript IV reverse transcriptase, the Ct value can be reduced by as much as 8. This enzyme outperforms wild type reverse transcriptases with better sensitivity at lower target concentrations. And it shortens the reaction time to just 10 minutes.
Inhibitors in Reverse Transcriptase Reaction
The reverse transcription step is a major source of variation in RT-qPCR. With SuperScript IV VILO Master Mix, the RT-qPCR workflow is sensitive and fast with highest cDNA yields, which enable more efficient and reproducible data.
Reverse Transcriptase Reaction in 10 minutes — Enzyme Processivity
SuperScript IV reverse transcriptase is the most robust reverse transcriptase with increased processivity and more resistant to reaction inhibitors such as guanidinum, heparin and salt as compared to wild type reverse transcriptases.
Overcoming RT-qPCR challenges
