Invitrogen™ SuperScript™ III One-Step RT-PCR System with Platinum™ Taq High Fidelity DNA Polymerase
Description
The SuperScript III One-Step RT-PCR System with Platinum Taq High Fidelity is designed for convenient end-point detection and analysis of RNA molecules by one-step RT-PCR. This one-step formulation allows for both cDNA synthesis and PCR amplification to be performed in a single tube using gene-specific primers and target RNAs from either total RNA or mRNA. It also allows for the detection of a wide range of RNA targets (up to 10 kb in length) at variable concentrations (1 pg to 1 μg of total RNA). This system consists of two major components: SuperScript III RT/Platinum Taq High Fidelity enzyme mix and 2X reaction mix.
SuperScript III RT is not significantly inhibited by ribosomal and transfer RNA and can be used to synthesize cDNA from total RNA. Platinum Taq DNA Polymerase High Fidelity is a an enzyme mixture composed of recombinant Taq DNA polymerase, Pyrococcus species GB–D polymerase, and Platinum Taq antibodies, which block polymerase activity at ambient temperatures enabling hot start PCR.
The 2X reaction mix consists of a proprietary buffer system optimized for reverse transcription and PCR amplification, Mg2+ optimized for universal use, deoxyribonucleotide triphosphates, and stabilizers.
The SuperScript III One-Step RT-PCR System with Platinum Taq High Fidelity offers:
• High-fidelity end-point detection and analysis of RNA molecules by RT-PCR
• PCR amplification and cDNA synthesis in a single tube
• Detection of a wide range of RNA targets from 300 bp to 10 kb
• Increased specificity with wide cDNA synthesis temperature range of 45−60°C
Note: For superior one-step RT-PCR performance, we recommend the SuperScript IV One-Step RT-PCR System (Cat. No. 12594025) or SuperScript IV One-Step RT-PCR System with ezDNase (Cat. No. 12595025). The SuperScript IV One-Step RT-PCR System combines the high processivity of SuperScript IV Reverse Transcriptase with the high-fidelity of Platinum SuperFi DNA Polymerase to provide unmatched product yields, specificity, and sensitivity in less time and for a broad target range, even with suboptimally pure RNA samples.

Frequently Asked Questions (FAQs)
We recommend using ezDNase (Cat. No. 11766051). ezDNase Enzyme's high specificity for double-stranded DNA enables efficient and fast genomic DNA removal without reduction in the quality or quantity of RNA. ezDNase Enzyme is heat-labile and so can be easily deactivated by heat treatment at moderate temperature (55 degrees C). These features make ezDNase Enzyme an excellent choice for genomic DNA removal prior to reverse transcription reactions.
The amount of RNA template for a cDNA synthesis is highly flexible and depends upon the amount of sample available and an individual's need. In general, 1 µg total RNA is used in a typical 20-µL RT reaction.
RNase H treatment is not always necessary. Many PCR reactions work without it. However, for cDNA synthesized with RNase H-deficient reverse transcriptases (like SuperScript II, III, and IV), RNA/cDNA hybrids—especially GC-rich ones—may not denature well, reducing PCR sensitivity. RNase H treatment can help in such cases. Additionally, RNase H treatment is beneficial for cloning larger fragments.
This depends highly on the quality of the sample. mRNA itself makes up 1-5% of total RNA. Depending on the primer and enzyme used, reverse transcription can covert >70% of that into cDNA.
Random primers are the best choice for degraded RNA, RNA with heavy secondary structure, non-polyadenylated RNA, or prokaryotic RNA. It is recommended only for two-step RT-PCR, and typically gives the highest yields, although the cDNA may not necessarily be full length. Oligo(dT) primers are good to use when trying to recover full-length cDNA from 2-step RT-PCR. The reaction is influenced by secondary structure and RNA quality. Gene specific primers should be used for very specific, mainly one-step RT-PCR reactions.
