Uncover the RNAs that retroviral reverse transcriptases miss. Switch to the UltraMarathonRT-powered cDNA Synthesis & Amplification Kit
RNA-seq is a powerful method for studying gene expression, but commonly used retroviral reverse transcriptases (e.g., MMLV and AMV) lack two critical properties for effective reverse transcription: intrinsic helicase activity, which enables the unwinding of complex RNA secondary structures, and high processivity, which allows for the synthesis of full-length cDNA from long RNA molecules.
UltraMarathonRT (uMRT) is a reverse transcriptase enzyme designed to overcome these limitations and improve RNA coverage. The cDNA Synthesis & Amplification Kit, powered by uMRT, combines intrinsic helicase activity with ultraprocessivity to efficiently reverse transcribe long RNA sequences (>30 kb—compared to the ~2 kb typically transcribed by retroviral RTs), as well as RNA with high GC content, complex structures, or low abundance. uMRT also functions at lower temperatures, helping preserve RNA integrity and enabling a more comprehensive view of the transcriptome.
