Reverse transcriptase reaction in 10 minutes—enzyme processivity

SuperScript IV RT has very high processivity and requires less time to generate full-length cDNA compared to wild type enzymes. With SuperScript IV RT it is possible to perform cDNA synthesis in only 10 minutes.

Inhibitors in reverse transcriptase reaction

Inhibitors can significantly impair the efficiency of reverse transcription reactions. Greatly improved processivity of SuperScript IV RT allows cDNA synthesis even in the presence of common inhibitors such as guanidinium and salts.

Understanding reverse transcriptase—effects on Ct value

SuperScript IV RT outperforms wild type RTs with better efficiency and sensitivity. Therefore, with SuperScript IV RT, the Ct value can be significantly reduced compared to wild type enzymes in RT-qPCR applications.

Overcoming RT-qPCR challenges

Sensitivity and dynamic range in reverse transcription are important factors for accurate quantitation in RT-qPCR. Learn the top 5 reasons for reduced sensitivity and high variability in RT-qPCR applications, and how SuperScript IV VILO Master Mix can help to overcome these challenges.
