SuperScript IV Reverse Transcriptase (RT) is a proprietary MMLV mutant with superior robustness and reliability in RT reactions. It is significantly improved over SuperScript III RT in inhibitor resistance, processivity, and reaction speed, while retaining all the benefits of that enzyme, including increased thermostability, highly efficient full-length cDNA synthesis, and reduced RNase activity. SuperScript IV RT is designed to provide reliable, consistent, and fast cDNA synthesis in the presence of inhibitors found in a wide variety of samples that cause other currently available RTs to perform inefficiently.

SuperScript IV RT offers advantages at standard as well as elevated temperatures over cloned AMV and ThermoScript RT, including higher sensitivity, inhibitor tolerance, and ability to work with degraded RNA.

Features of SuperScript IV Reverse Transcriptase include:
• Significantly improved resistance to inhibitors that can interfere with cDNA synthesis
• Robust and specific cDNA synthesis in a wide range of sample types
• Faster reverse transcriptase reaction reduces incubation time from >50 minutes to 10 minutes
• Better processivity when compared to SuperScript III RT

SuperScript IV RT is the top choice for all RT-PCR and qRT-PCR applications in the SuperScript product family when reproducibility and reliability is the primary concern. It is also our top performing RT when inhibitors in the RNA sample may interfere with cDNA synthesis, leading to biases in gene expression studies.

Source
Purified from E. coli expressing the pol gene of M-MLV, modified to increase thermostability and half-life, processivity, inhibitor resistance and to reduce RNase H activity

Unit definition
One unit of SuperScript IV RT is the amount of enzyme required to incorporate 1 nmole of deoxyribonucleotide into acid-precipitable material in 10 min at 37°C using poly(A) oligo(dT)12-18 as a template/primer.

Unit reaction conditions
50 mM Tris-HCl (pH 8.3), 4 mM MgCl2, 10 mM DTT, 50 mM KCl, 0.5 mM dTTP, 0.4 MBq/mL [3H]-dTTP, 0.4 mM poly(A) oligo (dT)12-18 and enzyme in 20 μl for 10 min at 37°C.
