Genomic DNA Removal*
Efficient cDNA Synthesis
Easy One-Step Setup
Super Simple
All-In-One 5X RT MasterMix with gDNA Removal is a convenient and ready-to-use formulation for first-strand cDNA synthesis with an easy one-step setup that reduces pipetting and sample handling. Simply add your RNA sample with our mastermix and incubate.

Accurate cDNA Synthesis
Genomic DNA contamination is a common problem for accurate RNA detection and this MasterMix solves that problem without affecting reverse transcription and first-strand cDNA synthesis. cDNA synthesis will be simple, reliable, and reproducible.

OneScript® Hot Reverse Transcriptase

Synthesise cDNA from complex RNA templates with abm’s OneScript® Hot Reverse Transcriptase. Engineered for outstanding thermostability, their OneScript® Hot Reverse Transcriptase is ideal for handling secondary structures (e.g. GC-rich templates) as well as long, degraded, or contaminated RNA samples, making it the superior choice for challenging RNA templates.

Extreme thermostability At 50-80°C
Transcribes degraded samples and resists inhibitors/contaminants
High cDNA yields from difficult or ultra-low RNA samples
Outstanding Thermostability

OneScript® Hot Reverse Transcriptase has exceptional thermostability. OneScript® Hot Reverse Transcriptase (Cat. No. ABM-G593) was used in a 10 min. reaction with RNA template at temperatures ranging from 50 and 80˚C. The resulting synthesised cDNA was followed by PCR and visualised on a 1% agarose gel.
OneScript® Plus Reverse Transcriptase

Routine cDNA synthesis can be completed in just 10-15 minutes with abm’s OneScript® Plus Reverse Transcriptase! OneScript® Plus Reverse Transcriptase has improved thermostability and is engineered for high cDNA yields, high efficiency on low-input, long, or difficult RNA templates, and resistance to inhibitors and contaminants.
