The Invitrogen SuperScript One-Step RT-PCR System, available with or without ezDNase, combines the high processivity of SuperScript IV Reverse Transcriptase (RT) with the high-fidelity of Platinum SuperFi DNA Polymerase to provide unmatched one-step RT-PCR performance. With this convenient one-step formulation plus gene-specific primers, you can perform both cDNA synthesis from total RNA or mRNA and PCR amplification in a single tube.

Features of the SuperScript IV One-Step RT-PCR System include:
• Superior performance with sensitivity down to 0.01 pg RNA, target length up to 13.8 kb, and the fastest one-step RT-PCR protocol
• Reliable target detection even with suboptimally pure RNA samples
• Two-phase hot-start activation mechanism for high sensitivity, specificity, and room temperature setup
• Fast and easy gDNA removal for superior accuracy and confidence in results (SuperScript IV One-Step RT-PCR System with ezDNase only)

SuperScript IV RT is a proprietary MMLV RT mutant with increased processivity, thermostability, and inhibitor resistance, as well as reduced RNase H activity, for sensitive and efficient full-length cDNA synthesis. Platinum SuperFi DNA Polymerase is a proofreading DNA polymerase that combines superior fidelity with trusted Platinum hot-start technology for the highest success in PCR. The combination of these two engineered enzymes produces enhanced RT-PCR yields and fidelity, as well as amplification of longer templates compared to other one-step RT-PCR kits.

The inclusion of ezDNase (SuperScript IV One-Step RT-PCR System with ezDNase only) for use upstream of the RT step further enhances the one-step RT-PCR workflow through an extremely simplified genomic DNA removal step that ensures the highest accuracy and confidence in one-step RT-PCR results.

Frequently asked questions (FAQs)

In your SuperScript IV RT protocols, there is no ezDNase inactivation step. Will active ezDNase affect RNA or the RT reaction?

The Invitrogen ezDNase Enzyme is a novel DNase that is highly specific for double-stranded DNA. It has no activity on single-stranded DNA in RT reactions (primers or probes), or on RNA. The enzyme is also thermolabile—it is inactivated quickly at temperatures typical for the SuperScript IV RT reaction (e.g., 50°C). The additional inactivation step is therefore not required in RT-qPCR applications.

Which SuperScript IV RT format do you recommend for real-time PCR applications?

For RT-qPCR applications we recommend using the Invitrogen SuperScript IV VILO Master Mix (Cat. No. 11756050). The cDNA synthesis reaction setup with this master mix requires fewer pipetting steps and therefore reduces variation in the data. SuperScript IV RT, as a component of the master mix, offers the highest efficiency of cDNA synthesis step compared to competitors’ products.

Are there any significant changes in the SuperScript IV RT protocol compared to the SuperScript III RT protocol?

The only change is that the incubation time for the reverse transcription reaction has been reduced from 50 minutes to 10 minutes. All the other parameters and steps are the same.

Can I get comparable cDNA yield and length using the SuperScript IV RT 10-minute protocol as when using the 50-minute protocol for SuperScript III RT?

When compared with SuperScript III RT (and other manufacturers’ RTs) in a synthesis reaction for a 9 kb cDNA, SuperScript IV RT performed successful synthesis in just 10 minutes and did so with comparable (or improved) yield (as shown by gel band density).
