iScript™ IV Reverse Transcriptase

Introduction

iScript™ IV Reverse Transcriptase (RT) is a novel MMLV mutant with superior robustness and reliability in RT reactions. It exhibits much higher efficiency in the first strand cDNA synthesis from RNA templates with secondary structures and high GC contents. The iScript™ IV Reverse Transcriptase is engineered to work under high temperatures (50°C-55°C), which can further facilitate to resolve the secondary structures and high GC problems of RNA. Besides, the iScript™ IV Reverse Transcriptase is significantly improved in inhibitor resistance, processivity, and reaction speed. iScript™ IV RT is designed to provide reliable, consistent, and fast cDNA synthesis in the presence of inhibitors found in a wide variety of samples.

The enzyme is available in 5,000 and 20,000 unit sizes at a concentration of 200 U/µL. The enzyme is supplied with a 5× Reaction Buffer.
