● Magigen RT enzyme Features
Magicscript Reverse Transcriptase, RTase II, is a recombinant DNA polymerase. It is a product of the pol gene of Moloney Murine Leukemia Virus （M MLV）. Based on the reduction of RNase H activity , genetically engineered, Magicscript Reverse Transcriptase II works perfect over a wider temperature range with higher thermal stability and longer half-life.
● Unit Definition
One unit is defined as the amount of enzyme that will incorporate 1 nmol of dTTP into acid-insoluble material in 10 minutes at 37°C using poly(rA)•oligo(dT) as template/primer.
● Storage Conditions and Expiration
Sealed at-20℃, valid for 12 months.
● Product Performances
Comparing Magicscript RT-II with same products from both domestic and oversea suppliers under same reacting conditions of 42℃ and 55℃, the results present reliability and stability, especially the superiority in higher temperature zone.
● Magicscript Reverse Transcriptase II Advantages
1. A wider thermal resistance range of 37°C to 65°C compared with other M-MLV product, and high activity. The residual activity retains at least 70% after 30 min in the high temperature range of 55°C to 65°C.
2. Work with kinds of reaction buffers, compatible with one-step reaction systems such as RT-PCR\RT-RDA\RT-Lamp\RT-HDA.
3. Show a perfect linear relationship between the different RNA concentration and the cDNA yield.
● How to use thermostable Reverse Transcriptase II
Example: first strand cDNA synthesis
Reaction System Vol ( µl)
Thermostable RTase II 1
5× Reaction Buffer 1 4
100 mM DTT 2
RNase Inhibitor（20-40 U/µl） 1
dNTP Mix ( 25 mM each) 1
primer 10μM-250μM

● Reaction steps
1. gently mix the reaction system;
2. recommended reaction procedure:
Temperature Time
25℃1 2min
45℃ 30min
85℃ 2min
*1. This step is only required when using random hexmers;
● RTase II Kit Application
The obtained cDNA can be directly used for 2nd strand cDNA synthesis or PCR amplification.
● Heat Inactivation
80°C for 20 minutes
● Note
1. The optimal temperature range of magicscript thermostable reverse transcriptase II is 37-45 ℃, Its RNaseH activity was one-third that of wild-type MLV. When the temperature is higher than 45 ℃ (lower than 65 ℃), the residual activity will decrease correspondingly with the increase of temperature, but at least 70% of the activity can still be maintained.
2. When using this product for one-step RT-PCR experiments, it is recommended to add the following components to the complete PCR system (including templates, specific primers and other components) that researchers have:
Reaction System Vol ( µl)
Thermostable RTase II 1
RNase inhibitor（20-40 U/µl） 1
Final volume 20-25
Suggested reaction procedure:
45-50℃ 15 min
