PureScript II Pro Reverse Transcriptase is a new generation reverse transcriptase optimized from the M-MLV (RNase H ) Reverse Transcriptase. Compared with the previous generation reverse transcriptase, the thermo-stability of this product is significantly improved. The half-life of PureScript II Pro Reverse Transcriptase at 50°C is >240 min. At 55°C, the half-life of the enzyme is >1 hour, which significantly benefits the transcription of RNA templates with complex secondary structure. In addition, it has an improved template affinity and cDNA synthesis efficiency. It has a good resistance to most RT-PCR inhibitors and is suitable for long-fragment cDNA amplification (up to 20 kb). PureScript II Pro Reverse Transcriptase is applicable for reverse transcription of animal, microbial, and plant RNA rich in polysaccharides and polyphenols.
