Product Description
igScript™ Glycerol-free Reverse Transcriptase is a recombinant Moloney Murine Leukemia Virus (MMLV) reverse transcriptase with reduced RNase H activity. It is highly efficient at producing full-length cDNA from long RNA templates. igScript RT is an RNA-directed DNA polymerase which lacks 3´ → 5´ exonuclease activity and is capable of producing cDNA from as little as 50 pg of total RNA for real-time RT-PCR analysis and other applications.
Protein Purity:
The physical purity of this enzyme is ≥98% as assessed by SDS-PAGE with Coomassie® blue staining (see figure below).
Product Source
The gene encoding recombinant MMLV Reverse Transcriptase with mutated RNase H domain is expressed in E. coli.
Applications
- First strand cDNA synthesis for PCR or RT-PCR
- Gene expression data validation by using RT-PCR
Benefits
- Recombinant MMLV reverse transcriptase with greatly reduced RNase H activity.
- Active at temperatures up to 55°C.
- Highly efficient at producing full-length cDNA from as little as 50 pg of total RNA.

Unit Definition
One unit is defined as the amount of enzyme required to incorporate 1 nmol of dTTP into acid insoluble material in 10 minutes at 37 °C using poly r(A)/oligo (dT) as a substrate.
Heat Inactivation
65°C for 20 minutes.
First Strand cDNA Synthesis Protocol
- In a sterile micro-centrifuge tube, add the following components on ice: reverse-transcriptase-pic2.
- Heat the reaction for 5 minutes at 65 °C. Spin down briefly. Place the tube immediately on ice.
- Add the following components: reverse-transcriptase-pic3.
- If using random hexamers, incubate the reaction at 25 °C for 10 minutes, then proceed to step 5.
- Incubate the reaction at 42 °C for 30–60 minutes.
- Inactivate the enzyme by incubating at 65 °C for 20 minutes.
- Store products at -20 °C or proceed to the next step.
