New England Biolabs' WarmStart RTx Reverse Transcriptase

New England Biolabs has released a novel, thermostable reverse transcriptase called WarmStart RTx Reverse Transcriptase that is designed for use in reverse transcription loop-mediated isothermal amplification, RT-PCR, and other applications for detecting low-quantities of target RNA from complex sample matrices. WarmStart RTx is reversibly inhibited at room temperature, and is activated when warmed above 40° C, which enables researchers to set up their reactions at room temperature with no background reverse transciptase activity.
