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.

● 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


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:
