HiScript II Reverse Transcriptase is a new generation reverse transcriptase optimized from the M-MLV (RNase H-) Reverse Transcriptase. Compared with the last generation reverse transcriptase, the thermo-stability of this product is significantly improved. The half-life of HiScript II Reverse Transcriptase at 50℃ is >240 min. At 55℃, it can also be stable for a long time, which significantly benifits the transcription of RNA templates with complex secondary structure. In addition, it has a 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 (as long as 20 kb).
