Well suited to structured, degraded, low-input, or inhibitor-containing RNA and workflows that benefit from elevated reverse transcription temperatures.
Flexible RT for routine cDNA synthesis
Designed for reliable first-strand cDNA synthesis across routine RNA samples, including long RNA templates.
| Characteristic | OneScript® Hot | OneScript® Plus |
|---|---|---|
| Best suited for | Challenging, structured, degraded, low-input, or inhibitor-containing RNA | Routine and flexible cDNA synthesis |
| Thermostability range | 50–80°C | 50–55°C |

G592 Performance
G592 formulation dataBuilt-In Genomic DNA Removal
G592 combines temperature-sensitive DNase and reverse transcription in one 5X MasterMix to reduce genomic DNA interference before downstream analysis.
qPCR
Reduce gDNA-Driven Early Amplification
Built-in gDNA removal helps reduce amplification from contaminating genomic DNA.
In the GAPDH assay shown, contaminating genomic DNA produced earlier amplification, which can complicate downstream interpretation. G592 integrates genomic DNA removal before reverse transcription in the same workflow to help reduce this source of signal.
Gel
Compare cDNA After gDNA Removal
Gel comparison shows cDNA after G592 gDNA removal versus a workflow without built-in removal.
This agarose gel compares a genomic-DNA-contaminated RNA sample processed with G592 against a competitor RT MasterMix without built-in genomic DNA removal. The figure illustrates the effect of removing genomic DNA before cDNA synthesis under the conditions shown.
G590 Stability
G590 stability reportReady-to-Use MasterMix Stability
G590 was evaluated after repeated freeze-thaw cycles and short-term storage at 4°C and 20°C using downstream qPCR.
Full functionality after 20 freeze-thaw cycles and 7 days at 4°C
A decrease in activity was reported after 3 days at 20°C, so the product should still be stored at −20°C as specified.

Reverse Transcription FAQs
Quick answers for choosing a chemistry, reagent format, or specialized workflow.
How is RNA converted to cDNA?
During first-strand cDNA synthesis, reverse transcriptase uses RNA as a template to synthesise complementary DNA (cDNA). The cDNA can be used in downstream PCR, qPCR, and gene expression analysis. Researchers can choose a cDNA synthesis kit, ready-to-use RT MasterMix, or reverse transcriptase enzyme depending on their workflow.
Should I choose OneScript® Hot or OneScript® Plus?
Choose OneScript® Hot for structured, degraded, low-input, or inhibitor-containing RNA and workflows that benefit from higher reverse transcription temperatures. Choose OneScript® Plus for routine and flexible cDNA synthesis.
Which product should I use if genomic DNA contamination is a concern?
G592 combines genomic DNA removal and reverse transcription in one 5X MasterMix, making it the direct starting point when gDNA may interfere with downstream PCR or qPCR.
When should I choose G590 instead of G592?
Choose G590 when you want a ready-to-use OneScript® Hot 5X RT MasterMix and built-in gDNA removal is not required. Choose G592 when gDNA removal is part of the workflow.
What is the difference between a cDNA kit and an enzyme-only product?
cDNA kits provide the supporting components for a complete reverse transcription workflow. Enzyme-only formats are better suited to custom reaction design.
Can I use total RNA or poly(A)+ mRNA?
Yes. OneScript® cDNA workflows support both total RNA and poly(A)+ mRNA.
Do I need to add a separate RNase inhibitor?
OneScript® reverse transcription products include RNaseOFF Ribonuclease Inhibitor, so an additional RNase inhibitor is generally not required for these formulations.
Is G597 for RT-qPCR?
G597 is designed for end-point one-step RT-PCR rather than one-step RT-qPCR.
What is different about G898 for miRNA?
G898 is a specialized miRNA cDNA synthesis workflow that combines polyadenylation and reverse transcription in a single-tube reaction.
