igScript™ Reverse Transcriptase (igScript RT) 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.
The physical purity of this enzyme is ≥98% as assessed by SDS-PAGE with Coomassie® blue staining (see figure below).
The gene encoding recombinant MMLV Reverse Transcriptase with mutated RNase H domain is expressed in E. coli.
