HelixCript™ Thermo Reverse Transcriptase, a thermostable and RNase H-negative variant of M-MLV reverse transcriptase (RTase), is an enzyme to synthesize cDNAs from RNA templates at a temperature range of 42 ℃ ~ 55 ℃ and shows the highest activity at 50 ℃. The high processivity and productivity of Thermo Reverse Transcriptase can synthesize cDNA up to 12 kb from an RNA template.
